This feels like papering over the problem.

If this codepath was written like this (i.e. [PATCH 1C]) from the
beginning, I would have found it very sensible (i.e. instead of
caling exit() in the middle of the infinite client serving loop,
exiting the loop cleanly is easier to follow and maintain), even if
we didn't know the issue on Cygwin you investigated.
