* @brief Tests uniprocessor-specific semaphore behaviour.
*
* This test case performs the following actions:
*
* - Create a worker thread and two MrsP mutexes. Obtain the Mrsp mutexes and
* check that a task yield works (owner is not sticky). We need two mutexes
* since the uniprocessor schedulers do not increment the stick level in the
* scheduler unblock operation.
*
* - Yield and let the worker obtain the MrsP mutexes.
*
* - Yield and let the worker release the MrsP mutexes.
*
* - Clean up all used resources.
