I've always wondered why some BSD's don't swap. Having a thrashing
machine crash is a terrible disaster.
My AT&T SysVr3.2 3b2/500, with 4 Mb of RAM, can run emacs-19, pathalias
on the world, news, mail, and uucp, and still grind along and get things
done.... It uses the page 'til I thrash, then swap away, style of VM.
