0068  *   for requirements of the @ref RTEMSAPIClassicTasks.
0069  *
0070  * This test case performs the following actions:
0071  *
0072  * - Validate the home scheduler of tasks created by rtems_task_create() and
0073  *   constructed by rtems_task_construct() on scheduler B.
0074  *
0075  *   - Move runner from scheduler A to B.
0076  *
0077  *   - Create a task.  Check that the home scheduler of the created task is
0078  *     scheduler B.
0079  *
0080  *   - Construct a task.  Check that the home scheduler of the constructed task
0081  *     is scheduler B.
0082  *
0083  *   - Restore runner scheduler.
