This is the latest state of play with this patch. I have been developing it
for -ck and ported it to 2.5 if anyone is still interested. Basically it will
make a task interactive faster than vanilla and will prevent a task losing
it's interactivity status for longer.
The added changes include a small workaround for integer division, and a new
feature - non linear boosting.
I have implemented a sigmoid curve shaped boost to the priority boost. This
makes it harder for tasks to get the largest priority boost or the greatest
penalty. Basically cpu hungry tasks that remain cpu hungry but fluctuate in
their sleep time due to lots of other tasks running will get less priority
boost and fluctuate less in that boost also.
Feel free to test it and comment. Things to look for - the dreaded audio skip
under load, and X remaining interactive during sustained use under load.
