    sys/kern             kern_switch.c 
  Log:
   - Add three new functions to support circular run queues.
   - runq_add_pri allows the caller to position the thread at any rqindex
     regardless of priority.
   - runq_choose_from() chooses the lowest priority thread starting from a given
     index.  The index is updated with the rqindex of the chosen thread.  This
     routine is used to pick the lowest priority relative to a given index.
   - runq_remove_idx() updates the index if the run queue that held the removed
     thread is now empty.
