It has made things better here too.  I'm not sure the "big lock"
approach is all roses though.  I now see stalls where a slow DNS
server answering the first query blocks all other queries.  At least
now things eventually clear (usually after a minute) instead of
hanging forever.

I'm still not sure why BIND didn't like the 3 queries on one UDP src
port.  I asked about this on comp.protocols.dns.bind but the usenet
posts are still awaiting a moderators stamp of approval.
