No, this patch didn't change anything either.

IIRC I get failures while free(1) shows as much as 20MB free RAM
(ie. without buffers/caches). Additionaly nr_free_pages (from
/proc/vmstat) stays at about 800-1000 under heavy memory pressure
(gitk on full linux repository).

Hmm, I wonder if it's really timing issue then wouldn't be the case
that lowering swappiness sysctl would make problem more visible?
I've vm.swappiness=15, would testing with higher value make any sense?

Thanks.
