I doubt that's a problem right now.  Right now my office is pretty
chilly, and it was even cooler last night while these were running.
This is the first time I've seen these "*** Signal 6"s, and this
is also the first time I've tried a USE_KQUEUE verison of `make'.
And while the make-related processes died with the signal's, none
of the other processes on the system had any problems.  (including
the folding-at-home client which is still running on the machine).

Also, this machine is usually running two copies of the "folding at
home" client, so it is *usually* running flat-out, 24 hours a day.

There are other days when the air-conditioning in the computer
center is a bit flaky, and my office gets up to 90F.  This machine
hasn't had any problems at those temperatures (although I sometimes
do!).
