some bad thinking on my part.

Good enough?

from a name resolve. Without this, we leak memory!

might change it. I don't *think* it does it when the timeout is 0,0 but it
is better to be sure...

DEBUG_THREADING_GETHOSTBYNAME is defined

This works by magicly starting up a new thread that can be killed when the
timeout is reached. testtesttest!

seems to correct some host cache screw-ups I could reproduce.

systems.

NOTE that this breaks ares-compatibility, we have now officially taken the
turn into the c-ares path. We will now officially depend on c-ares for asynch
name resolves.

as well, and when failing and not getting a timeout we now include the
error message ares can provide us with.
