The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/841efc17964ac66ffa6b8b5ff63436f4ff6d52c1 commit 841efc17964ac66ffa6b8b5ff63436f4ff6d52c1 Author: mattcary <mattcary@chromium.org> Date: Wed Jan 11 16:21:04 2017 Prerender: avoid race condition with canceling prerender in test. The test which started flaking started two prerenderers, the second which canceled the first. ChromeOS in particular exposed a race condition where the first prerender would complete before the second had a chance to cancel it. This in retrospect obvious situation exists elsewhere and has an easy fix in a HangingFirstRequestInterceptor which stalls the first prerender indefinitely, causing it to be reliably canceled by the second.
