Perhaps we should break free from thinking about virtual memory in the
first place.  What about programs and files "permanently" resident in
memory.  I believe that once one starts thinking this way, the uses of 
large memories are abundant - disk access is slower than memory.  Also
the lack of the hardware and operating system overhead to support 
virtual memory could speed up processing.
