[SDL] OS X + SDL_SetEventFilter = Bus Error

Yes, I believe the documentation states that you should never call SDL
video API functions from the event filter thread.  It may be called from
another thread or from a hardware interrupt.

Instead you should either send another SDL event or set a global variable
or use some other messaging system to notify anyone who cares.

See ya,
