Processes will not get swapped out until memory pressure occurs. Thus,
idle processes waste physical memory until this situation occurs.
Physical memory is always a valuable commodity, and should IMHO be
reclaimed whenever possible.
It makes even more sense to page out idle _pages_ instead of processes,
but I don't know if it is even possible to determine how long a page has
been idle, in terms of clock time.
