| Creates a semaphore and two processes. The processes |
| each go through a loop where they semdown, delay for a |
| random amount of time, and semup, so they will almost |
| always be fighting for control of the semaphore. |

| sem02 |
| The application creates several threads using pthread_create(). |
| One thread performs a semop() with the SEM_UNDO flag set. The |
| change in sempaphore value performed by that semop should be |
| "undone" only when the last pthread exits. |
