Not only this, but the number of users also expands.  One thing often
overlooked, I think, is that with a paging system, assuming adequate
locality of reference, you can have a large number of pages resident that
are actively in use by a large number of users, instead of having great
unused expanses of memory allocated to large programs at any one time,
keeping other users out of memory.
