I hope everyone realizes that all of this bike-shedding about emulated semaphores versus "real" semaphores is mostly a non-issue.  For one thing,  go look at how a "real" semaphore is implemented by reading the source code to pthreads or some other thread library.  You'll find that semaphores are implemented using the exact same mechanisms that underly condition variables and in some cases, are actually implemented using a mutex lock and a condition variable exactly as Python is doing.

Second, the performance of using "real" semaphores still sucks.   So, all of the arguing about "fairness" and whatnot seems to be a total waste of time in my opinion because it doesn't address the underlying problem.
