Looking at that, I'd go strace bind (if it's not too busy that is). The
tcpdump shows that all its questions were answered at the point of the
delay, so it must be busy playing with itself somehow -- unless it tries
to first send a query through another interface (one you didn't snoop
on), but of course a strace will tell you that anyway.
Sorry if this is all too obvious...
Cheers,
Emile.
