Here is a small patchlet.

It is possible tasks were getting more sleep_avg credit on requeuing than they 
could burn off while running so I've removed the on runqueue bonus to 
requeuing task. 

Note this applies onto O16.3 or 2.6.0-test3-mm3 as O17 was dropped.

This patch is also available here along with a patch against 2.6.0-test3:

this patch still makes my xmms skip on light io load (untar kernel
source, open lkml mailbox folder) while opening mozilla. Even after
mozilla is there xmms is still skipping. Processes take ages to spawn.
And no, I'm not in swap. A 'su -'is taking 10 seconds to procceed.
Same applies when rm -Rf'ing a kernel tree.
Here is some more data for the curious:

note the load of 11. I can even get it to 30 while doing 3 tar xf
bla.tar simultanously.

I'm going to fetch some fish in the next two weeks in poland, so I will
not be able to do any more testing from sunday on. Happy coding (while I
stick to O10 *g*)

Thanks for comments. ]

There it is again; the reference to darn O10. Hrm. One question before your 
holiday; your O10 kernel is it the same kernel tree or a different/newere 
one? I'm looking to blame something else here I know but I need to know; this 
just doesn't hold with any testing here.

well, I run O10 on top of test2, since I didn't need any patches from
test3 I didn't rediff it.

Okay, I applied O18 on top of test2 now. Xmms works as a charm,
programm start is still slow while doing an tar xf linuxtest2.tar.
Already open xterm's (one with mutt) react a bit in-interactive (I spawn
vi to write this email and a :w takes 5 seconds). It is nonetheless
worse than O10, sorry to say that.

Ok, but none of that weird starvation and massive load and skipping audio. 
Interesting. At least it's clear now that all is _not_ just my patches. 
Thanks for testing.

Unfortunately, the procps fork is getting even bigger now... :(

I don't see an option for this in debian's package.

I have been using 2.6.0-test3-mm3 plus O18int for a whole day and I must
say that, for me, O18int is the best I've seen until date. I dare to say
I think it's even better than O10int.

I'll second that, the priority inversion issues I was having with 
2.6.0-test3-mm2 are completely gone!  I haven't been able to get any 
serious inversion issues to bring the system to its knees yet, but I'll 
keep trying.  The only difference is that I've disabled sound in order 
to use the latest kernels, but I don't think that probably had anything 
to do with the inversion problems I was running into.

And after using 2.6.0-test4 vanilla for a few hours I have a new 
appreciation for the improvements that come with Con's patches...
