Why no ProcessScheduledActions()?

[brianderson, 2014/04/11 20:49:40]

I guess it wouldn't hurt, but today this will only be called within a callstack
where we are already in a ProcessScheduledActions.  Also, a DidSwapBuffers()
should not trigger any new actions, only throttle some.

I'll add a comment, since I would consider it a bug if we need to call
ProcessScheduledActions here to make proper progress.
