| // 1. Write our strings to the first region |
| // 2. Ensure that our peer hasn't signalled the second region. That would |
| // indicate that it didn't wait for our interrupt. |
| // 3. Send the interrupt on the first region |
| // 4. Wait for our peer's interrupt on the first region |
| // 5. Confirm that we can see our peer's writes in the first region |
| // 6. Initialize our strings in the second region |
| // 7. Send an interrupt on the second region to our peer |
| // 8. Wait for our peer's interrupt on the second region |
| // 9. Confirm that we can see our peer's writes in the second region |
| // 10. Repeat the process for signaling. |
| // 11. Confirm that no interrupt is pending in the first region |
| // 12. Confirm that no interrupt is pending in the second region |
