Actually, release can be SetEvent because the mutex logic only needs a binary semaphore, or an event on windows. However, I cannot remember if an event is "faster" than a semaphore on windows or not. Still do not know how windows handles it's futexes wrt internal impl. WaitOnAddress and such.
A semaphore is not signifiantly but measurable faster.
