    If after that message everything worked fine, yes this should be the
    normal behavior (I think ;-).

    Right now I am changing some things in the patch (not that the old one was
    completly wrong but there was very good reasons to run shrink_mmap() for
    more than num_phys_pages because the page aging (I didn' t thought at
    that some days ago)).

    Note that the really important part of the patch are the
    __get_free_pages() changes and the kswapd changes. Other things are minor
    issues. Without that changes the system die, with that changes the system
    live.

    And swapoff -a seems to have problems. It' s not safe (even if the system
    doesn' t deadlock anymore, but there _seems_ to be a race between swapoff
    and the swap cache if during swapoff the system is swapping out a lot (I
    have to think about it reading the code though so I am not sure right
    now...)).
