First, the FAQ doesn't really explain why this problem happends. Personally I have a hostname in my /etc/hosts so there is obviously another factor involved. I suspect if the name is resolvable by DNS you might get different results. Why DNS should have anything to do with binding 127.0.0.1 I don't know but there's not much I can do about it.

Anyway, I'll apply the below fix. That should pretty much eliminate the problem regardless.
