the only true fix is DNSSEC.  meanwhile we'll do UDP port randomization,
plus we'll randomize the 0x20 bits in QNAMEs, plus we'll all do what
nominum does and retry with TCP if there's a QID mismatch while waiting for
a response, and we'll start thinking about using TKEY and TSIG for
stub-to-RDNS relationships.

but the only true long term fix for this is DNSSEC.  all else is bandaids,
which is a shame, since it's a sucking chest wound and bandaids are silly.

all we're trying to do is keep the 'net running long enough to develop
and deploy DNSSEC, which would be much harder if updates.microsoft.com
almost never points to a microsoft-owned computer.
