Ah, I think you're right.  So actually, the retry looping is expected
to be never-invoked in the Unix case.  If it did happen, it'd be a busy
wait loop, which would probably be a bad thing ... but it shouldn't
happen, and not clear it's worth adding any code to consider the
possibility more carefully.
