Let's try the "refill_inactive() also does VM scanning" approach, as that should make sure that we are never in the situation that we haven't taken the virtually mapped pages sufficiently into account for aging. I'm making a 2.4.6-pre2 as I write this, give it a whirl. I've been working with "mem=64M" for a change to verify that it's not obviously broken. Compared to my 1GB setup it obviously doesn't cach the kernel trees quite as well, but it seems to be fairly pleasant to work with nonetheless. (It is hard for me to judge - it's been some time since I last used a 64M machine for any amount of time ;) Please, try things out. We need to have a better feel for the balancing heuristics.
