Good.  I assumed that was what you meant, but I wanted to be sure.

And that leaves me quite puzzled.  It is of course possible that Opera
and Firefox uses different host name resolution strategies, but there's
not really that many "correct" ways to do it.  The choice essentially
boils down to "call one of the libc functions".

Didn't we use to have a --debugdns switch, by the way?  Maybe that could
sprinkle some twilight over the problem?
