Pete, the system already does this.  If a resource is listed as "purgeable"
then the system will "unload" it if more memory is required.  Admittedly
MultiFinder doesn't dynamically reallocate memory for programs, but this
is one of its first incarnations -- when Apple does add this feature, then
you can be guaranteed that people will bitch because the system takes up
too much meomory, a price we will all have to pay if we want mainframe
and minicomputer performance out of a microcomputer.

So waddya want?  The universe on a dime budget?  Not even Apple can
deliver *THAT*!
