    My thinking was allong these lines. At a given instant in time the max we
    have that might get swapped out is the inactive list. So if we start
    aggressive swapping when we have less swap than the size of the inactive
    list we should be ok. The premise being that leaving swap mapped can be
    a win for pages swapped in but not changed.
