It would assign certain types of use to certain
zones of memory and do so dynamically.

Ie. we'd have a 4MB zone allocated to kernel and
pagetable stuff and other areas assigned to
user pages. Now when we need to have another kernel
data area we can move pages out of one of the user
area's as needed. We can also move out arbitrarily
large chunks of contiguous user pages if we need
to allocate such an area.
