There's no reference to the loopback interface in that line, just abstract and unix domain socket references. So this does not require the presence of "localhost" in /etc/hosts to work. Maybe we should simply run a strstr on SESSION_MANAGER looking for "localhost" prior to complaining about being unable to resolve "localhost". That should do the trick.
