* \b test_start

* Start queue test.
*
* With multiple threads blocking on a single queue, this test confirms that
* they are woken in order when the queue is posted. The correct order for
* waking is that the higher priority threads are woken first, followed by the
* lower priority threads. Where multiple threads of the same priority are
* waiting, the threads are woken in FIFO order (the order in which they started
* waiting on the queue).
*
* To test this we create four threads which all wait on a single queue.
* One pair of threads are running at high priority, with the other pair at a
* lower priority:
*
* Thread 1: low prio thread A
* Thread 2: low prio thread B
* Thread 3: high prio thread A
* Thread 4: high prio thread B
*
* The threads are forced to start blocking on the same queue in the
* above order.
*
* We expect to see them woken up in the following order:
* 3, 4, 1, 2
*
* This proves the multiple blocking thread ordering in terms of both
* the priority-queueing and same-priority-FIFO-queueing.
