    I don't use swap prefetch (nor -ck or -mm). If someone who has the patch
    applied waits to hit enter until swap prefetch has prefetched it all back in
    again, it certainly will.

    Swap prefetch's potential to do larger reads back from swapspace than a
    random segfaulting app could well be very significant. Reads are dwarved by
    seeks. If this program does what you wanted, please use it to show us.

    Rene.
