[issue5099] subprocess.POpen.__del__() AttributeError (os module == None!)

[Brett Cannon]

Brett Cannon <brett at python.org> added the comment:

Attached is a patch I wrote entirely independently of this issue (Mercurial's test suite trigger it for me). I go further in terms of caching items than the original patch as I still got failures even when I stored just a reference to os (might be an OS X thing with the os module).

I just need someone to verify my patch works under Windows. If someone can do that I will commit it and Gabriel's test (with Antoine's suggested fixes).
