Which reminds me of another thing I noticed--MPEnter/ExitCriticalRegion
seemed to be a lot slower than the raw pthread solution, according to
Shark. Why is this? Seems like one should be just as good as the other.


Interesting. I would have thought they'd be close too.

FWIW, it appears that MPTask-based locking is significantly slower than the Windows equivalent (though I don't have anything like Shark on the Windows side to really compare).

In general, any time I could get rid of a mutex (or semaphore, I'm probably using these terms sloppily) I could get measurable improvements in our apps. --
