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.
