And what was the older Mac OS doing? Spinning down the hard disk? Turning
off the display? I think they're doing very similar things. One thing for
sure, processes are all halted when the Mac goes to sleep in OS X. Also, OS
X being based on Unix, I'm not sure that they can spin down the hard disk
and expect it to be off because the OS with virtual memory and such could
need the hard disk at any time. So, for all these reasons, I think that OS X
pretty much turn off everything, including the processor, hard disk, etc,
pretty much like the old Mac OS was doing. However, as I pointed out and as
somebody also pointed out, when AppleTalk is turned on on the old Mac OS, it
will take several seconds before you can start using the Mac, while on OS X,
it is instantaneous.

On low-end personal machines without an MMU (or Windows boxes, which have an MMU but use it incompetently), this can corrupt the OS itself, causing massive lossage. Other frenetic dances such as the cha-cha or the watusi, may be substituted.
