+ * This is an implementation of the global fixed priority scheduler (G-FP).  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.  Since the processor and priority count are constants all
+ * scheduler operations complete in a bounded execution time.
+ *
+ * The thread preempt mode will be ignored.
