 Test Number 15 (F):

 This test verify the correctness of the PI module.


 the main task (NRT) lock a PI mutex.
 then 2 tasks arrives, with priority higher than the main

 the first try to lock the mutex, but it can't, so the main inherit
 his priority. The second simply prints a string.

 If all works, the string of the second task is printed after the end of
 the first task.
