Well, there is os.fork in Cygwin and SUA (SUA is the Unix subsytem in Windows Vista Professional). Cygwin's fork is a bit sluggish. Multiprocessing works on Windows and Linux alike. Apart from that, how are you going to use threads? The GIL will not be a problem if it can be released. Mostly, the GIL is a hypothetical problem. It is only a problem for compute-bound code written in pure Python. But very few use Python for that. However, if you do and can afford the 200x speed penalty from using Python (instead of C, C++, Fortran, Cython), you can just as well accept that only one CPU is used.
