As I said previously, you also need to make the current standard handles non-inheritable. Pending issue 19764, in 3.7 you'll be able to override stdin, stdout, and stderr with the default close_fds=True. Currently overriding them implicitly sets close_fds=False, in which case you need to manually ensure that the current standard handles (i.e. the pipe handles) can't be inherited. For example:

    os.set_inheritable(0, False)
    os.set_inheritable(1, False)
    os.set_inheritable(2, False)
