SIGTERM handler: use _exit(2), not exit(3) 

exit(3) is not async-signal safe (presumably due to atexit(3) processing),
so use _exit(2) instead. This was clearly an omission from the original
code which even had a comment to the effect that _exit(2) needed to be
used. In all likelihood this never caused any problems as atexit(3)
functionality is not used.
