Ah, sorry, I wasn't clear: this does not *have* to break when you are outside
your LAN.  My laptop doesn't, for example, which is good.

Some of these things happen inside glibc, I am afraid, so the answer is
typically "with difficulty".  I don't know specifically what in Emacs is
triggering the behaviour, though.

I would suggest ensuring that your host has an entry in /etc/hosts for the
hostname you use, though, which should reduce the problem.  Alternately, you
could tune down the DNS lookup time.

All die.  Oh, the embarrassment. ;)
