I beleive something like this can be done/has already been done as a daemon.
The daemon would sleep most of the time, but once in a while (60
seconds?) wake up and check the amount of free virtual memory. If not
enough is availlable (user-configurable), then create a new swapfile (of
size user-configurable, and only if there's enough disk space availlable).
When there's plenty of free virtual memory (also user-configurable), then
the daemon can remove a swapfile.
This should be easy to code if it doesn't exists... I might even be
interested in doing it :-)
