* - Dequeue one object, two objects, MAX_BULK objects
* - Check that dequeued pointers are correct
*
- * - Test watermark and default bulk enqueue/dequeue:
- *
- * - Set watermark
- * - Set default bulk value
- * - Enqueue objects, check that -EDQUOT is returned when
- * watermark is exceeded
- * - Check that dequeued pointers are correct
- *
- * #. Check live watermark change
- *
- * - Start a loop on another lcore that will enqueue and dequeue

- * - At the same time, change the watermark on the master lcore.
- * - The slave lcore will check that watermark changes from 16 to 32.
