+	 *	An event buffer maintains an in-memory buffer of events.  When this buffer is full
+	 *	it sends to buffer to all handlers registered and resets the buffer.
+	 *
+	 *	It is parameterized in four ways.  The first is a context provider that provides
+	 *	both thread id and context id.
+	 *	
+	 *	The second is the mutex (which may be null) and a scoped locking mechanism.  Thus the buffer
+	 *	may be used in a multithreaded context but clients of the buffer don't pay for this if they
+	 *	don't intend to use it this way.
+	 *
+	 *	Finally the buffer may use an event filtering mechanism.  This mechanism needs one function,
+	 *	namely isEventEnabled( uint8_t subsystem, uint8_t eventId ).
+	 *
+	 *	All of these systems can be parameterized at compile time leading to an event buffer
+	 *	that should be as fast as possible given the constraints.
+	 *
+	 *	Buffers may be chained together as this buffer has a handleBufferFlush method that
+	 *	will grab the mutex and add the data to this event buffer.
+	 *
+	 *	Overall, lets look at the PhysX SDK an how all the pieces fit together.
+	 *	The SDK should have a mutex-protected event buffer where actual devs or users of PhysX
+	 *	can register handlers.  This buffer has slow but correct implementations of the
+	 *	context provider interface.
+	 *
+	 *	The SDK object should also have a concrete event filter which was used in the
+	 *	construction of the event buffer and which it exposes through opaque interfaces.
+	 *
+	 *	The SDK should protect its event buffer and its event filter from multithreaded
+	 *	access and thus this provides the safest and slowest way to log events and to
+	 *	enable/disable events.
+	 *
+	 *	Each scene should also have a concrete event filter.  This filter is updated from
+	 *	the SDK event filter (in a mutex protected way) every frame.  Thus scenes can change
+	 *	their event filtering on a frame-by-frame basis.  It means that tasks running
+	 *	under the scene don't need a mutex when accessing the filter.
+	 *
+	 *	Furthermore the scene should have an event buffer that always sets the context id
+	 *	on each event to the scene.  This allows PVD and other systems to correlate events
+	 *	to scenes.  Scenes should provide access only to a relative event sending system
+	 *	that looks up thread id upon each event but uses the scene id.
+	 *
+	 *	The SDK's event buffer should be setup as an EventBufferClient for each scene's
+	 *	event buffer. Thus the SDK should expose an EventBufferClient interface that
+	 *	any client can use.
+	 *
+	 *	For extremely *extremely* performance sensitive areas we should create a specialized
+	 *	per-scene, per-thread event buffer that is set on the task for these occasions.  This buffer
+	 *	uses a trivial event context setup with the scene's context id and the thread id.  It should
+	 *	share the scene's concrete event filter and it should have absolutely no locking.  It should
+	 *	empty into the scene's event buffer which in some cases should empty into the SDK's event buffer
+	 *	which when full will push events all the way out of the system.  The task should *always* flush
+	 *	the event buffer (if it has one) when it is finished; nothing else will work reliably.
+	 *
+	 *	If the per-scene,per-thread event buffer is correctly parameterized and fully defined adding
+	 *	a new event should be an inline operation requiring no mutex grabs in the common case.  I don't
+	 *	believe you can get faster event production than this; the events are as small as possible (all
+	 *	relative events) and they are all produced inline resulting in one 4 byte header and one
+	 *	8 byte timestamp per event.  Reducing the memory pressure in this way reduces the communication
+	 *	overhead, the mutex grabs, basically everything that makes profiling expensive at the cost
+	 *	of a per-scene,per-thread event buffer (which could easily be reduced to a per-thread event
+	 *	buffer.

+		*	An event buffer maintains an in-memory buffer of events.  When this buffer is full
+		*	it sends to buffer to all handlers registered and resets the buffer.
+		*
+		*	It is parameterized in four ways.  The first is a context provider that provides
+		*	both thread id and context id.
+		*
+		*	The second is the mutex (which may be null) and a scoped locking mechanism.  Thus the buffer
+		*	may be used in a multithreaded context but clients of the buffer don't pay for this if they
+		*	don't intend to use it this way.
+		*
+		*	Finally the buffer may use an event filtering mechanism.  This mechanism needs one function,
+		*	namely isEventEnabled( uint8_t subsystem, uint8_t eventId ).
+		*
+		*	All of these systems can be parameterized at compile time leading to an event buffer
+		*	that should be as fast as possible given the constraints.
+		*
+		*	Buffers may be chained together as this buffer has a handleBufferFlush method that
+		*	will grab the mutex and add the data to this event buffer.
+		*
+		*	Overall, lets look at the PhysX SDK an how all the pieces fit together.
+		*	The SDK should have a mutex-protected event buffer where actual devs or users of PhysX
+		*	can register handlers.  This buffer has slow but correct implementations of the
+		*	context provider interface.
+		*
+		*	The SDK object should also have a concrete event filter which was used in the
+		*	construction of the event buffer and which it exposes through opaque interfaces.
+		*
+		*	The SDK should protect its event buffer and its event filter from multithreaded
+		*	access and thus this provides the safest and slowest way to log events and to
+		*	enable/disable events.
+		*
+		*	Each scene should also have a concrete event filter.  This filter is updated from
+		*	the SDK event filter (in a mutex protected way) every frame.  Thus scenes can change
+		*	their event filtering on a frame-by-frame basis.  It means that tasks running
+		*	under the scene don't need a mutex when accessing the filter.
+		*
+		*	Furthermore the scene should have an event buffer that always sets the context id
+		*	on each event to the scene.  This allows PVD and other systems to correlate events
+		*	to scenes.  Scenes should provide access only to a relative event sending system
+		*	that looks up thread id upon each event but uses the scene id.
+		*
+		*	The SDK's event buffer should be setup as an EventBufferClient for each scene's
+		*	event buffer. Thus the SDK should expose an EventBufferClient interface that
+		*	any client can use.
+		*
+		*	For extremely *extremely* performance sensitive areas we should create a specialized
+		*	per-scene, per-thread event buffer that is set on the task for these occasions.  This buffer
+		*	uses a trivial event context setup with the scene's context id and the thread id.  It should
+		*	share the scene's concrete event filter and it should have absolutely no locking.  It should
+		*	empty into the scene's event buffer which in some cases should empty into the SDK's event buffer
+		*	which when full will push events all the way out of the system.  The task should *always* flush
+		*	the event buffer (if it has one) when it is finished; nothing else will work reliably.
+		*
+		*	If the per-scene,per-thread event buffer is correctly parameterized and fully defined adding
+		*	a new event should be an inline operation requiring no mutex grabs in the common case.  I don't
+		*	believe you can get faster event production than this; the events are as small as possible (all
+		*	relative events) and they are all produced inline resulting in one 4 byte header and one
+		*	8 byte timestamp per event.  Reducing the memory pressure in this way reduces the communication
+		*	overhead, the mutex grabs, basically everything that makes profiling expensive at the cost
+		*	of a per-scene,per-thread event buffer (which could easily be reduced to a per-thread event
+		*	buffer.
