    This is worth posting to lkml so I've cc'ed a few relevant people (there
    is already a thread about this there). Rik care to comment? I recall
    pointing out this test case a while back. Got any way to make it harder
    to trigger the swap token? It seems to affect normal workloads adversely
    considering how rare swap thrashing actually occurs.
