Due to extreme lack of free time, I'm asking what The CPUs set the "accessed" bit in hardware, and that should be enough to do proper aging. If setiathome is all in RAM it means it gets touched more fast than netscape. BTW, I suggest you to try out: ftp://ftp.suse.com/pub/people/andrea/kernel-patches/2.2.9_andrea-VM4.gz and see if the swapout behaviour changes.
