- * _Thread_Rotate_Ready_Queue
- *
- * This kernel routine will rotate the ready queue.
- * remove the running THREAD from the ready chain
- * and place it immediatly at the rear of this chain. Reset timeslice
- * and yield the processor functions both use this routine, therefore if
- * reset is true and this is the only thread on the chain then the
- * timeslice counter is reset. The heir THREAD will be updated if the
- * running is also the currently the heir.
- *
- * Input parameters:
- * Priority of the queue we wish to modify.
- *
- * Output parameters: NONE
- *
- * INTERRUPT LATENCY:
- * ready chain
- * select heir
