|

* 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.
