Are those DNS queries that just take a lot of time, or that get stuck?

Ethereal remembers the result of a DNS query, so it shouldn't be
querying for any name more than once - and it remembers negative
results, so it shouldn't be retrying queries that timed out or otherwise
failed.  However, I still see "ethereal -n" loading significantly faster
than "ethereal" on files that I don't *think* have a boatload of
different IP addresses in them.
