Thanks! I've used the patch to test some servers

I've tested against:
- unbound
- dnsmasq
- powerdns-recursor
- bind9.7

All of these returned pipelined queries that I threw at them (upto a
few hundred)

OpenDNS worked as well.

Google DNS worked but puts a limit of 64 queries on a TCP connection.

I have not yet tested how long these servers and services keep idle
connections open.
