I can confirm that the patch fixes the problem on Windows (running test_ctypes
before test_multiprocessing).

However, the patch did not apply cleanly to current SVN trunk - I had to manually
patch the code.  I'll attach the patch that I have now when I run 'svn diff' as
multiprocessing.patch (hope it works, sending as email attachment).
