There was a major change in the peer selection algorithm to make it work
with tcp_outgoing_address across multiple address families.

I'm adding some debug now so we can view the selections and see what is
going on a bit better.

The patch is here:

More DIRECT requests are failing due to TCP connect or DNS lookup errors
than are succeeding.

Probably a side effect of (1) above.

Okay. Found this one. Sorry for being so dense earlier. I was looking at
the logic rather than the variable name :(

BTW: would you mind trialling with IPv6 enabled now? This version is
supposed to resolve all the edge cases previous releases had.

The only issues I'm expecting to be still relevant are:
  * servers not responding to IPv6 TCP packets (ECN and PMTUD issues).
  * DNS resolvers not responding to AAAA lookups.

Thank you. That should have been 17,2.

Just the debug tracer for when a request is about to be forwarded on
somewhere.
