I agree that this is an annoying bug, and I'm glad that it doesn't occur in the 27-maint branch.

I won't close this issue yet though, I'd prefer to add a unittest that demonstrates the problem in 2.7.0 and shows that the problem is fixed afterwords.

Basically something like this:


   pid = os.fork() 
   if pid == 0:
       # child
       import platform
       import urllib
       urllib.get_proxies()
       os._exit(0)

    else:
       # parent
       exit = sys.waitpid(pid, 0)
       self.assertEquals(exit, 0)
