Hello Kristjan, > This depends entirely on the platform and primitives used to implement the GIL. > I'm interested in windows. Could you try ccbench (*) under Windows? The only Windows system I have here is a qemu virtual machine and it wouldn't be very realistic to do concurrency measurements on it.

Hi, I just want to stress, that according to my test, the current GIL implementation works as intended on windows. But if we were to reimplement it, say using a CriticalSection, then yielding the GIL as we do in sys.checkinterval wouldn't work as intended anymore. Just something to keep in mind in case anyone is thinking along those lines.
