I am not sure I agree with you on this point.  I beleive that MOSIX
actually allows you to do something like that, although the units you
add or drop are whole physical machines and not just single CPU's or
memory blocks.

If it is sufficient to be able to add or drop physical machines from a
networked cluster of machines that make up the Multics site, then I
don't see it as a problem.
