I HAVE done it but...I havn't needed to do it in a LONG time.
Only ever had to resort to it once.

Yes that should do it...hmm...I seem to remember something about sync'ing
twice....

hmm Yes thats true and AFAIK that wasn't always the case. There
used to be (and are on other Unixes) halt and reboot which do just that.
in fact on them "sync;sync;reboot" is a traditional method for reboot :)
hmmm maybe we need "realhalt" and "realreboot"...
