This is another side of the missing split-stack support.

The particular DNS issues he mentions are, I believe, resolved by the
split-stack support currently in 3.HEAD. However, there are issues
further down in forwarding still to be resolved before I'm happy
back-porting it.

What was that old 3.0 saying? "Real soon now".

Meanwhile there is a perfectly working solution with --disable-ipv6 and
rebuild Squid.
