I'm still working on my SCHED_PFAIR stab. Expect an RFC someday soon

pfair is a deadline-driven algorithm that also executes the tasks at a 
steady rate, minimizing jitter as well as meeting deadlines. This give 
tasks better expressiveness when it comes to instructing the scheduler how 
to treat the task. I'll give a more formal intro in the upcoming RFC :)
