}-Actually, the big potential win on "compressed VM" is not in disk
}-_space_, even on local disks; local disk is cheap.

}-It's in disk accesses, which are incredibly slow, even compared to the
}-time it takes to uncompress a page on a "reasonable" cpu.

}-On faster CPUs (oh, say, like the 233MHz 21064As sitting next to me),
}-then the difference becomes even greater.

And the real kick in the idea is that it's neat and the feeling
you get when it finally works is XTC ;-)
