I'll see what I can do, but it will probably be a couple days to figure out how to measure it (e.g. without accidentally measuring any swap-to-disk). -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
