| michael@0 | 4 | Test that high-priority processes downgrade the CPU priority of regular |
| michael@0 | 5 | processes. |
| michael@0 | 6 | |
| michael@0 | 7 | This is just like test_HighPriorityDowngrade, except instead of waiting for the |
| michael@0 | 8 | high-priority process's wake lock to expire, we kill the process by removing |
| michael@0 | 9 | its iframe from the DOM. |
