-"""The page cycler benchmark.
-
-This benchmark registers a window load handler in which is forces a layout and
-then records the value of performance.now(). This call to now() measures the
-time from navigationStart (immediately after the previous page's beforeunload
-event) until after the layout in the page's load event. In addition, two garbage
-collections are performed in between the page loads (in the beforeunload event).
-This extra garbage collection time is not included in the benchmark times.
-
-Finally, various memory and IO statistics are gathered at the very end of
-cycling all pages.
