    Yeah, I've been focusing so much on getting the SMP case right that I've
    been neglecting UP a bit.

    I'm not overly fond of this one, either; I did it at Roland's suggestion
    (it's all _his_ fault, yeah, _that's_ the ticket! :-); his opinion IIRC
    was that the UP case will perform better without the extra pointer
    dereferences. I agree that it's a potential source of pain such as the
    one you point out.
