I wouldn't be so sure. The thread that's blocked waiting would pretty 
much be asleep so the main program is getting a boost while it's holding 
the lock. Once it unlocks, it should pass control to the waiting thread 
since it left prematurely before.

That looks ugly... I'd be content just warning to yield or rest every 
loop iteration if you're doing a lot of operations on the screen/video 
bitmaps.
