| 5 This file creates a large DOM tree in the live document that also contains |
| 6 event listeners. It then detaches the tree at the root. Since no JS |
| 7 reference is kept, the tree should be collected by v8 at some point in the |
| 8 future. As a result, if graphing DOM node and event listener count over time, |
| 9 we expect to see a "sawtooth" pattern that does not show any overall tendency |
| 10 to increase. |
