    I cannot repeat the experiment (due to lack of time) but i remember
    having severe issues with low /proc/*/swappiness values on vanilla
    kernels. I don't recall the nature of the problems, though, because it's
    been a while. Sorry. But that was what prompted me to search further.
    The search ended when i found and tested Con's patch.

    The current swapping policy of the vanilla 2.6 kernels is broken. Badly.

    At least my system works properly now. <shrug>
