8  * @file measure time for various FIFO operations
11  * FIFO operations from both kernel threads and user threads:
12  *  1. Immediately adding a data item to a FIFO
13  *  2. Immediately removing a data item from a FIFO
14  *  3. Immediately adding a data item to a FIFO with allocation
15  *  4. Immediately removing a data item from a FIFO with allocation
16  *  5. Blocking on removing a data item from a FIFO
17  *  6. Waking (and context switching to) a thread blocked on a FIFO via
19  *  7. Waking (and context switching to) a thread blocked on a FIFO via
