Yeah, I see no need to do anything about this on an emergency
basis.

The buildfarm's wait_timeout option isn't that helpful here, because
when it triggers, the client just goes belly-up *with no report*.
So even if the CCA animals had it on, you'd not notice unless you
started to wonder why they'd not reported lately.

I think that's a bug that ought to be fixed.  I do agree that
wait_timeout ought to be finite by default, too.
