Bug 54605

http/tests/security/cross-frame-access-child-explicit-domain.html is flaky on the Chromium Win Debug bot (see http://test-results.appspot.com/dashboards/flakiness_dashboard.html#showExpectations=true&group=%40ToT%20-%20chromium.org&tests=http%2Ftests%2Fsecurity%2Fcross-frame-access-child-explicit-domain.html ). This is because the test internally puts setTimeout(..., 2000) blocks around attempts to load frames. This is a recipe for flakiness. Test harnesses can kill long-running tests anyway, so it seems like we'd do better to just eliminate these timeouts entirely.
