[issue32220] multiprocessing: passing file descriptor using reduction breaks duplex pipes on darwin

[Antoine Pitrou]

See https://bugs.python.org/issue6560 for the original issue delineating the problems we had with fd passing on macOS.

I don't know whether Apple finally fixed the underlying issue.  If that was the case, I assume we might be seeing "unexpected successes" in test_socket?  Ned, Ronald, is that right?

Nate, if you want to investigate the underlying issue and see whether the workaround is still needed and/or another workaround is possible, your help is welcome.
