I think the point Martin is making (hopefully not putting words in
his mouth) is that he doesn't know of anywhere that he configured
localhost as a DNS resolver. You would expect (or at least I would)
that without any configured DNS server, DNS queries would just fail,
not try to contact random servers in case something answered.
