[issue5099] subprocess.Popen.__del__ causes AttributeError (os module == None)

I'm -1 on Brett's patch: keep a reference to the required functions in the function arguments is ugly to me. The process should be destroyed before unloading the modules. I don't know how (or even if it's possible or not :-)), but I think that Brett's patch is the wrong solution to the problem.

Eg. Can't we use atexit.register() to destroy the processes at exit?
