I reached 23 passes in SMP and nothing happened yet with my latest lru_cache code plus swap entry patch and classzone stuff. However I can't exclude it's a timing issue that doesn't allow me to reproduce. As soon as I'll have finished the rework of the swap entry logic as described in last email I'll pass you a patch to try out to see if you can reproduce something weird with it. Thanks.
