One big difference I've seen in past examples of paging systems
can be summarized as: page against everyone vs. page only against
oneself. The latter is sometimes called the "working set" model.
The former tends to make the whole system unusable when a process
lets its address space get out of control, while the latter tends
to run other processes pretty much the same under such conditions.
