* Instantiate new threads and set their priorities in decreasing order. Have the threads state their priorities as they execute and verify that they were run in decreasing order according to their priorities.
* Verify donation works by creating a high priority thread and joining it to a low priority thread with a high priority thread already queued.
* Create complex set of interdependent threads and multiple locks, verify that execution order is correct.
