Hmmm - this is the kind of thing that worries me slightly as our UPS
supply is limited (as anyones is).  If the UPS doesn't last as long
because I'm running SETI on 6 of our servers then I wouldn't be too
popular!  I'm not sure if the hardware/OS I use will have this increase
in power though.

Atleast on *nix, you can tie in events from the UPS straight into the init
process, which is probably the highest authority in your system short of
the kernel, and have it terminate seti immediately on loss of mains, and
restart seti if mains power is restored.
