"localhost" is assumed always to exist and to be bound to 127.0.0.1 (see
http://en.wikipedia.org/wiki/Localhost). You can of course give your
machine another name as well (just add additional names to the localhost
line in /etc/hosts), but you can't remove the meaning of localhost
without breaking things.
