Sorry I haven't been watching the bots; the signal 12 is new, I don't
have direct access to a fbsd box to poke at it. I'm fairly alarmed
that it's triggering that. Let me know what I can do to help - fbsd
support of certain lower level shared semaphore stuff has been spotty
up until the most recent versions.

If/when you do, please add me on the noisy list. I remember there
being some patche(s) pending for FBSD around improved shared semaphore
support, but I can't find the bug report right now.
