Or otherwise phrased: they're candidates to be paged out if something
requires that much memory soon. Meanwhile, stuff currently paged out will
stay there unless actively needed; why bother pulling it back in if nothing
actually needs it right now, especially since it got paged out because
nothing had used it recently (i.e. it was marked inactive)?
