Swap to ram?  I like the idea of /tmp (and /usr/tmp for that matter) on
a ram disk.  And then the system might benefit from having the pipe device
be a ram disk.  But swap space?  You're decreasing your available memory,
which causes more swapping.  It seems that just keeping that memory available
to programs would eliminate swapping almost entirely.

Besides, is ram really cheaper per megabyte than disk?  It seems really
unlikely now that chip prices are going back up.
