8 *  Test if the attributes specified by 'attr' are modified later, the thread's
9 *  attributes shall not be affected.
10 *  The attribute that will be tested is the detached state.
11 *
12 *
13 * Steps:
14 * 1.  Set a pthread_attr_t object to be PTHREAD_CREATE_JOINABLE.
15 * 2.  Create a new thread using pthread_create() and passing this attribute
16 *     object.
17 * 3.  Change the attribute object to be in a detached state rather than
18 *     joinable.
19 * 4.  Doing this should not effect the fact that the thread that was created
20 *     is joinable, and so calling the functions pthread_detach() should not fail.
