[New-bugs-announce] [issue5099] subprocess.POpen.__del__() AttribuetError (os module == None!)

New submission from Mary Stern <marystern at yahoo.com>:

I was getting this error (while running my unit tests):

Exception exceptions.AttributeError: "'NoneType' object has no attribute
'error'" in <bound method Popen.__del__ of <subprocess.Popen object at
0x8a2596c>> ignored

which I tracked down to the os module being set to None (yes really!) in
POpen._internal_poll() when called from Popen.__del__, so this line:

                    except os.error:

was generating the error.

I guess that the module is getting unloaded earlier somehow (maybe a
race condition)?
