    But with this "fix" you'd be adding another one in the
    process.

    Admitted, it's only a performance bug, but I found it to
    grind the machine to an absolute halt when doing IO
    intensive stuff or running large programs...

    Stephen Tweedie, Andrea Arcangeli and me have been looking
    at this bug and others and have found there's pretty much
    NO WAY to fix this without some bigger changes in the VM
    code. Performance will suck in the earlier 2.4 kernels, but
    I hope to have some new VM code ready later on for a more
    readable, better maintainable, more stable VM subsystem
    with somewhat higher performance.

    (I should write down the design we made at OLS and will do
    so shortly)

    regards,

    Rik
