    Note that we are not talking about having insufficient memory. In my
    case (2.4 kernel - ie, 2.6 with swapiness 0%) there is more than
    enough memory to contain all my working set - it's only because cache
    is too eager to claim memory that is otherwise in use that
    non-optimalities occur.
