How it's *supposed* to work is this...

If the machine hangs for 60 seconds, this will cause it to reboot.  The
device is supposed to be deactivated when heartbeat exits (and closes
/dev/watchdog).

And, in my tests, this is exactly how it works.  I have never seen it
shut the machine down in error.

However, I haven't used it in a few releases ;-)  I just reread the
shutdown code, and if it takes 60 seconds to shut down your resources
(long-running resources stop scripts), then this could happen.

However, if you're saying that 60 seconds after it said it was
completely shut down, that this happened, then I don't understand that.
