This seems much too repeatable to be hardware. The more times I
repeat my testing, the more consistent the problem seems. (but
I'll spare you the details until I narrow it down even more...).
I am sure I have rebuilt make several times, because I am switching
between "make WITH_KQUEUE" and make without kqueue, and I do
complete recompiles each time I switch. These signal-6's are not
coming up in "normal operation" for me. It is only when I have
been stress-testing changes to the make command.

No. I am not that adventurous when it comes to filesystems. I use
plain UFS2. I even turn off background FSCK-ing because I'm not
sure I trust it yet...
Please note that I did not mean to make a big deal about these
signal 6's. I have to go out-of-my-way to trigger the problem, but
now that I know what to do I can trigger it at will. Given that I
can repeat it I do intend to keep poking away at it, but I do not
consider this a serious issue. So unless a lot of other people
start reporting something similar, I do not expect anyone else to
spend any of their own time trying to pin it down. It's the kind
of annoying little anomaly that will drive me nuts unless I pin it
down, but in the greater scheme of things it is probably irrelevant.
I do appreciate the suggestions because they give me more ideas of
things I want to try when I have the time. But I don't expect
anyone to worry about this. Certainly I am not worried about it.
The main thing I wished to say was just "Great progress has been
made wrt using KQUEUE for make", given how well it has stood up
to my repeated hammering of it.
