(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.
