Well, if you have an UPS and the UPS has a power failure output, it wouldn't be
hard to write a program that performes a DosShutdown-call, or sends QUIT-
messages (or any other appropriate message) to the applications.  My opinion
is that there is sufficient possibilities to shutdown the system fast and
gracefully in such a situation.
