8 * Test that pthread_attr_setinheritsched() sets the inheritance of
9 * policy and priority.
10
11 * Steps:
12 * 1.  Create a pthread_attr struct using pthread_attr_init
13 * 2.  Set the inherit sched in it by calling pthread_attr_setinheritsched
14 * 3.  Change main's priority and policy
15 * 4.  Create a new thread.
16 * 5.  Check that it has correct priority and policy
