I added a short description:

  * This is an implementation of the global job-level fixed priority scheduler
  * (G-JLFP).  It uses one ready chain per priority to ensure constant time
  * insert operations.  The scheduled chain uses linear insert operations and
  * has at most processor count entries.
  *
  * The thread preempt mode will be ignored.

I will add more documentation later.  At the moment I don't have time and 
budget for this.

This is good.  I did my best to avoid copy and paste.

Yes.
