Do you mean lightweight processes by this?
I think that this discussion should be moved into csa.tech.

What?  I don't understand the question.  All things reside in the virtual
address space, which is considerably larger than the REAL address space
(ie, real RAM).

>3) Is virtual memory kept in a separate fixed size partition on the disk?

This is usually the case in most UNIX systems, and probably true of
Amiga UNIX.  I would prefer a separate small, fast disk (say 40 or 80 megs)
for paging so that disk thrashing is reduced.
