Hmm, this becomes better and better, but it's still not perfect [tm].

- An Xterm needs ~30 seconds to open up while "make -j16 bzImage modules"
- An Xterm needs ~15 seconds to open up while "make -j8 bzImage modules"
- XMMS does _not_ skip mp3's while above.
- Kmail is almost unusable while above (stops for about 5 secs every 15-20
secs). KMail is also very slow while the machine is doing nothing.
- X runs with nice 0, prio 15 (nice -11 is prio 4, does not make difference)

Over all, the whole system seems in a ~snail mode.

Andrew, two things:

1. I'll test it with high job numbers, because it _must_ be possible to use
that w/o any stops of xmms music, w/o X running like a dog etc.
2. I use anticipatory scheduler for sure. Best I've ever seen, never had
any problems. :)

ciao, Marc
