Ok, first thing to consider is that time.sleep in Python does in reality (on Debian Linux, Python2.3) a select syscall with 3 NULLs to wait the time. (The "real" sleep POSIX call might have stupid interactions with signals, to be specific SIGALRM) Don't have a Python source at the moment (I'm offline at the moment) to check how it's done in Win32. > I am in the process of writing a multithreading program and what I was > wondering is a sleep command in an executing function will affect the > threads below it?

Well, your program seems to be non-functional (missing if expression?), but as I said above, the main thread waits via select, so the child process should be able to run in this time (assuming time.sleep releases the GIL, but I'd file it as a bug if it doesn't).
