    I agree that process accounting is kind of random.
    However, it is exactly this randomness that makes
    me believe that it really isn't a measurement fault.

    Before the patch, xmms cpu usage varied between 70
    and 95%. Now it varies between 50 and 75%, this
    looks like too big a thing to be random.
