i used a similar method to correctly account resource usage
(cpu,energy,..) of processes in my diploma thesis:
work done by a sever (e.g. X) is accounted to the current client,
giving more resources to the server
http://admingilde.org/~martin/papers/

implementation is working but far from being mergeable...




RE: the patch, i think using sleep_avg is a wrong metric from the
beginning.

in addition, timeslices should be shortest for high priority processes
(depending on dynamic prio, not static)

but these are of course just simple statements and i don't have
a patch that makes a really good scheduler :(
