Would anyone care to comment on why we need virtual memory at all
with a 256 meg real memory being available in the near future?

I haven't seen a virtual memory system yet that would stand up
to one of my simulation programs when the program size exceeded
the physical memory size.  As soon as the system started paging
the performance was so out to lunch that you would have to wait
days for the program to complete and everyone would be on your
back for sending the machine to lunch.	Back when 1-4 meg is all you
had paging might have been important, with 16 meg on my personal computer
I don't see the need for it.
