The swapping of the uarea doesn't really introduce a lot of
extra complexity, since all it does is allocate swappable
pages, just like the swappable pages in user space.

Change that mode stuff out of the uarea are probably a bad
idea, since it increases KVA pressure by moving them to
wired kernel pages.
