But... what about the machine's other addresses?
If Windows doesn't treat 0.0.0.0 to mean listen on every interface,
that's a shame. But making it only listen on 127.0.0.1 and not any of
the others does not seem better. Then, instead of 0.0.0.0 failing on
Windows, it would instead work but with different behavior. That
doesn't seem good either.
