See http://test-results.appspot.com/dashboards/flakiness_dashboard.html#showExpectations=true&tests=http%2Ftests%2Fsecurity%2Fcross-frame-access-put.html .

This test's been renamed since this bug was filed and the flakiness is being seen on other platforms. Duping this bug.

Shoot, I misread the name of the failing test. Un-dup'ing.
