There's still a problem with the C resolver (which John appears to
have tracked down to a compiler bug), as pointing Net::DNS at one
of the other name servers (nic3.barrnet.net or nic.near.net)
successfully returns 817 records but "dig" still croaks.
So, I think there are 2 issues:
1. shields.burlee.com is confused, returning either SERVFAIL (my experience)
or misformatted records (Michael's experience)
2. The C resolver can't handle this answer if compiled with -O.
