    [...and hence should be reniced]

    The problem is that X is not unique. There's postgresql, memcached,
    mysql, db2, a little embedded app I wrote... all of these perform work
    on behalf of another process. It's just most *noticeable* with X, as
    pretty much everyone is running that.

    If we had some way for the scheduler to decide to donate part of a
    client process's time slice to the server it just spoke to (with an
    exponential dampening factor -- take 50% from the client, give 25% to
    the server, toss the rest on the floor), that -- from my naive point
    of view -- would be a step toward fixing the underlying issue. Or I
    might be spouting crap, who knows.

    The problem is real, though, and not limited to X.

    While I have the floor, thank you, Con, for all your work.
