I'm inclined to leave the blocking-connect change in there just to
suppress that peculiar error message. No, I have no idea where it's
coming from, either.

If the problem were overflow of the accept queue, then raising the
listen() parameter ought to fix it, assuming that Windows does actually
allow larger values for the parameter. Given that we are only hearing
this problem reported on Windows, I have a sneaking suspicion that the
effective queue length limit is 1 on that platform no matter what we
pass to listen(). Is there anyone we might ask about concurrent
connection-request handling on Windows?
