This is just a try build and not flaky on ToT bots.

This doesn't look like a trooper issue. Please re-add trooper label if you need machines restarted, etc.

Actually this test is also flaky on Waterfall, but it might pass after the 3 retries.

This shows the beginning of the flakiness by rerunning the test 100 times with build artifacts from Waterfall.

Disabled on windows due to repeated failures on win_chromium_x64_rel_ng and win_chromium_rel_ng.

lanwei@chromium.org: assigning to you since you enabled this test for windows in https://codereview.chromium.org/1692593002 and no one has worked on this test since. Please take a look or assign to a better owner.

It is also flaky on Win 7 Tests, where it times out.
