> Is reboot -h too ruthless? (I think it is)

If your software is written to exit gracefully on some signal
(SIGTERM==15, for example), you could try sending that to all such
processes, wait a little, and then reboot -h.  The man page for reboot
does not specify which signal it uses to kill processes, but I suspect it
is 9, which cannot be caught.
