OOMing doesn't help also, since kernel starts to swap and I have
performance degradation after. Swithching off the swap is dangerous in
conjunction with OOMing.
indirectly, patch mentioned in this mail can help:
http://marc.theaimsgroup.com/?l=linux-kernel&m=106142721228497&w=2
it provides a way to limit read cache - so it is easier to flush it.
P.S. will love to see something like this in 2.6. And for 2.4 too.
