No, I didn't want to imply that at all. Sorry if that came out wrong.
I'd put the stress on _reliably_.. I can't get Samba to fail that way.
If you can, and we can figure out how your set-up is different, that'll
help me to debug this. I'm just very surprised that whatever is
happening only goes away after the reboot, so samba seems to mess up
something at the kernel level. That's not supposed to be possible from
the user-space. The fact that this happens on multiple different
machines makes this even more curious.

No, the forwarder code was a pretty quick hack to make development of
some other DNS code easier while running the internal DNS on my dev
machine. I'm not expecting that to be bug-free at all. :) That said, the
current code in master should behave better.

Cheers,
Kai
