request drops in BIND?

BIND8 and BIND9 are both used on root name servers, which handle thousands
of requests per second (each), including mixtures of large and small ones,
and including "packet trains" of more than 178 requests back-to-back.  if
your system is dropping queries under that load, it's due to bad kernel
design, or bad kernel tuning, or inadequate hardware resources.
