[Pdns-announce] Important bug fix, PowerDNS 3.1.1 released...

[bert hubert]

With many thanks to Alessandro Bono for his excellent debugging.. The
increased security of PowerDNS 3.1 came at a hidden cost, if an A and an
AAAA query would be outstanding for the exact same domain, to the exact same
server, these queries would be merged, with sometimes very bad results.

This mostly happens for Konqueror users on hosts that have IPv6 lookups
enabled, but it might impact all users given enough time.

This did not show up in our big testing due to the relative scarcity of AAAA
lookups, and because most of the big test setups have quite some latency
with their users, which lessens the chance of having two simultanous queries
in flight.
