-DOC = """
-The basic premise here is to set up a deadlock scenario and confirm that PI
-mutexes resolve the situation. Three worker threads will be created from the
-main thread: low, medium and high priority threads that use SCHED_FIFO as
-their scheduling policy. The low priority thread claims a mutex and then
-starts "working". The medium priority thread starts and preempts the low
-priority thread. Then the high priority thread runs and attempts to claim
-the mutex owned by the low priority thread. Without priority inheritance,
-this will deadlock the program. With priority inheritance, the low priority
-thread receives a priority boost, finishes it's "work" and releases the mutex,
-which allows the high priority thread to run and finish and then the medium
-priority thread finishes.
-That's the theory, anyway...
