    Using a couple of processors (or more)

    I obviously harbor a lot of respect for Donald Knuth, but what he says in this interview (via /.) is plain wrong:
    The machine I use today has dual processors. I get to use them both only when I’m running two independent jobs at the same time; that’s nice, but it happens only a few minutes every week

    Beeeeep! Wrong. If you have a dual or quad processor, the OS is delivering processes to them all the time. So you're using all of them all the time. Right now I'm listening to music, and using a browser, while I'm running X and various widgets. That's only on the surface, deep down, there are a few dozens process running. So you're running two independent jobs (and scads more) all the time, and you get to use both processors all the time. Not to full capacity, of course (right now, my own processor only takes a 20% load), but you get to use them all the same.

    Indeed he does, but also rxvt and fvwm and gv and X and all that. It's not a matter of needing them, but actually using them, which he obviously does.
