    I will send it to you off-list. I've been avoiding to publish it for a long
    time because the stock scheduler was *very* sensible to trivial attacks
    (freezes larger than 30s, impossible to log in). It's very basic, and I
    have no problem sending it to anyone who requests it, it's just that as
    long as some distros ship early 2.6 kernels I do not want it to appear on
    mailing list archives for anyone to grab it and annoy their admins for free.

    Cheers,
    Willy
