Any thougts?  Is a 60% performance increase for the common case of acquiring an uncontested lock worth doing?

Btw, for our console game I also opted for non-semaphore based locks in thread_pthread.h, because our console profilers were alarmed at all the kernel transitions caused by the GIL being ticked....
