One _big_ vote for putting thread sync primitives --- events, 
semaphores, mutexes and critical sections --- in. We had to build a 
custom Wine to get acceptable realtime performance (thanks, Ulrich!). 
The client <-> server were causing high priority threads to block on low 
priority ones.

I guess a test case would be something that shows how a high priority 
thread blocking on a sync primitive, while some low priority thread is 
doing some unrelated server heavy stuff, like lots of graphics updates.

Cheers... mo
