There's a couple of threads about this from May 2007 or thereabouts
that you should be able to find in the list archives. (I know because
I started those threads.) The short answer seems to be that Xorg gets
annoyed if it can't resolve the local IP address to a hostname, and it
attempts to do this any time any application connects to the X server.
Other (non-X) apps will cause similar issues if they attempt DNS
operations for any reason while the network is down.
You can fix *most* of this by making sure that there are entries in
/etc/hosts for 127.0.0.1, etc., but I was never able to get the
problem to entirely go away in all circumstances.
