X gets unhappy if it can't map the hostname to a valid address, so that's bad
if you're running a laptop without net connectivity.

I've managed to get julliard to agree that we could try and work around that in
Wine. I can try and look into that and maybe get it into 1.0.

The basic idea would be to check if "gethostbyname" returns a loopback address
when the hostname isn't localhost. If it does, we return a special 127. address
instead of 127.0.0.1 or whatever the distro will set.

Then, when we see that magic 127. address in bind, we look up the interface
that has the default route and bind to the IP of the interface with the default
route.

Alexandre hinted he'd accept that approach and I think that's about as clean a
fix as possible.
