Even when the disk-cache-pages are more frequently used than the
program-text-pages? If I understand things correctly, a program has to
wait ~9ms when the data it needs is on the disk, whether its program text
or data. Also, programs often have pages that are *never* used after
startup; the sooner those pages are evicted in favor of useful things the
better.
