+
+ The init task UT1 should start on cpu 3 and has priority:affinity set
+ 7:{2,3} The test creates 4 more tasks TA1 - TA4
+ with priorty:affinity sets 8:{2,3}, 5:{0,1}, 6:{0,3}, and 9:{1}.
+ This should result in cpu:task 0:TA3, 1:TA2, 2:TA1, 3:UT1 with

+
+ The test then raises the priority of TA4 to 4, resulting
+ in the following cpu:task 0:TA2, 1:TA4, 2:UT1, 3:TA3 with
+ TA1 waiting on a CPU. The tasks are then terminated.
+
+ The capture engine is set up read and report the results. It should
+ show the task switches for a worst case migration of tasks.
