Hmm...if you really aren't using some pages, why not have them paged out during some idle time and have more free physical memory available immediately without having to wait for pageout, should demand occur? I don't know if Linux will ever page out even very old pages if there is no memory pressure at all, but it probably makes sense to do so in order to have memory available immediately, should a huge demand occur. Then again, should those pages be demanded again, you would have to wait for pagein. I wonder what Linux does?
