I'm suirprised that LOWMEM exhaustion causes oom-killer (when HIGH &
SWAP are half empty) but there you go, life is full of surprises ;)
Of course, it could be something else, but its definitely disk i/o that
triggers the oom-killer and clearing the cache stops it from happening
(2.6.31.12) - any alternative explain really really welcome.
