The cpu scheduler simply isn't broken as the people on this mailing list seem
to think it is. While my tweaks _look_ large, they're really just tweaking
the way the numbers feed back into a basically unchanged design.

For what it's worth, I haven't had any problems with Con's O19int. I've
been trying to repeat a case of priority inversion I experienced with
O18.1...but it seems to be cured (and that was really my only problem
with it). I was already getting fewer skips in XMMS with
2.6.0-test3-mm2 than I did with 2.4.18 and the same sort of workload. I
can't really test xmms now that the ACPI changes have obliterated my
chances of freeing IRQ 5 for my sb16 -- but from the improvements I feel
in the last few patches from Con, I imagine that it wouldn't skip
anymore. (On a side note, I really miss xmms where random means quite
random, unlike my CD changer which is repeat the same songs in a four
hour block.) I certainly am not running any sort of high-end machine
with a K6-2 400 ;-) The mouse might lag slightly for a few seconds when
starting up a build, but as soon as the scheduler adjusts, I can't tell
whether I have four builds running at the same time or just one. In
2.4.18, it has a slow feeling that let's you know the system is loaded
-- and it never goes away (well, until the compiling's done).
