2 This file is used as a control test to compare with the other Chrome Endure
3 tests in perf_endure.py.
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.
