I sincerely hope that the virtual memory in 7.0 IS NOT one large space
shared by all processes--just like my present Mac but with more memory.

That is the one thing I HATE HATE HATE about the Mac (which I am otherwise
crazy about :-)).  One errant program crashes the entire system.  To
come home from UNIX (with harmles core dumps) to the Mac (with heart-wrenching
system bombs) can be traumatic.  And even worse: you cannot tell which
program caused the crash! It might have been caused by a program you ran a
half hour ago (or at least that is my experience).

I would rather have the system and applications protected from each other
without any virtual memory than have TONS of virtual space with crashes
being that much more spectacular.
