Testing Windows' implementation of Python multiprocessing on Linux

Question

CPython's multiprocessing package is implemented fairly differently on Windows and on Linux, as a Windows implementation cannot rely on fork(2). However, it seems to me that the Windows implementation of multiprocessing (spawning a separate process and send it the required state by serializing it) should work on Linux (or am I wrong?).

While I work on Linux, I would like to make sure that the code I write also works on Windows (e.g., not accidentally have unpicklable arguments, etc.). Is there a way I can force CPython to use the Windows implementation of multiprocessing on Linux?

Thanks.

I don't think so. As you notice, the process model of Linux and of Windows are profoundly different. — Basile Starynkevitch

Hum, in fact this has just become possible very recently: http://bugs.python.org/issue8713. Now I just have to run 3.4alpha2 :)
