Putting the swap between two file systems on a single hard disk is
the default method that SCO uses.  It seems to work for them.

This goes along with the thinking of some other operating systems I
have used by putting frequently accessed tracks in a central
location, eg a part of the disk where the average access time is
the same - in those small OSes the directories were placed in the
center of the disk.

It would seem to be a logical place for swap, but I have not seen
(nor done) tests pointing to this.
