I have been writing a new scheduler off and on for several months now.
That was the motivation behind the sched_* api.  I intend to finish it up
and get it commited for 5.1.  It supports the following buzz words: ;-)

 - O(1) operation
 - Per cpu run queues
 - CPU binding
 - CPU affinity

In addition, I have a nice tool for testing various scheduler behavior.  I
have used this to prove that nice, for example, does the same thing with
my scheduler as it did with the old one.  I will probably commit this tool
as well.  It runs on linux and I have some interesting datapoints from the
linux scheduler.  I'll write this up at some point.

Cheers,
Jeff
