I think you could make a good case for that. VM provides for more
efficient use of physical memory, but there is nothing you can do on
a machine with 16Meg of RAM and 32Meg of swap that you couldn't do
on a machine with 48Meg of RAM and no swap.
On the other hand, protecting one process's memory from being corrupted
by another process is a sine qua non for an OS to pretend any sort of
reliability, and implementing that does most of what you need to implement
a VM system, so I can't see any good reason for an OS not to have VM.
