The kernel might page out some of your less frequently used pages in the process of faulting in new ones.

Not that I know of. This is a frequently-requested tweakable parameter, and while an ideal virtual memory system would never need to be tweaked by end users/administrators, I am a little surprised it isn't implemented, since I think few would claim the linux virtual memory system can't be improved further. :) (And no, Rik, I'm not volunteering to implement it myself. rmap meets my needs fine. :) -- Outlook users: please do not put my email address in your address book.
