I think the particular issue mentioned in 3864 is fixed, in some sense:
test_signal used to hang, but now just plain fails in a reasonable amount of
time (~15 seconds) instead. So at least the test_signal failure isn't
preventing us from seeing the results of other tests.
The big problem now on the FreeBSD buildbot is that test_multiprocessing
reliably causes the whole test run to abort with 'Signal 12'. Solving this
may be as simple as just getting someone to install a copy of FreeBSD 6.2
on an ssh-accessible machine so that the source of the error can be tracked

This error has been happening since well before 3.0 was released. Asking
for access to Neal's machine is probably the only sensible way to diagnose
it. (A less invasive but slower way to debug would be to create a branch
especially for this bug and do repeated runs to figure out which part of test_os
is causing the failure.)

It's not fixed, but I hope to have time to fix it this weekend. It's just
not showing up on some runs because test_multiprocessing kills the
buildslave first. :-)

Wholeheartedly agreed! Sorting out the FreeBSD test_multiprocessing
Signal 12 would be nice, too. I'll open an issue for this, unless
someone else gets there first.
