I think I remember it on the Silicon Graphics IRIS running SYSV 3.3.1 IRIX 
I played with for a while.  Anyway, I don't know if it had any battery or
special power supply... I don't *think* it did but I don't know... anyway,
it did send a SIGPWR once to one of my processes which logged it, but I made
no provision for it, and the system then actually rebooted, so my process was
lost.  No second SIGPWR signal or anything that I know of.

Note not to take my words as gospel; this was a while back and I wasn't 
paying exact attention to what happened.
