    Ooooh. We saw something like this, specifically when doing a "swapoff -a".
    As >25Mb were swapped out, the command took a while to complete. From the
    time the command was issued, until swap did indeed die, we had 0kb total,
    0kb free, and almost exactly 2Gb used(!).

    Apart from that, pre-2.0.31 + 5 fixes + seriously hacked and finally
    stable 3x59x driver, is running like a treat under at times pretty hefty

    Note that the sockets stuck in "CLOSE" I reported, are NOT a problem, and
    were related to a memory leak in an ethercard driver I hadn't patched with
    a "dev_kfree_skb".
