Getting bigger should be easy, probably just populating
the allocators, perhaps using extra rmaps for the
extra mem and doing something similar with the allocators on top.
Getting smaller may require assigning pages first from permanent
rmaps, to avoid relocating vm to the permanent ones.
But, is this part really needed?
