This kind of failure is well understood, and we may have older bugs tracking flakiness on other appcache tests. Due to the async nature of appcache, we can't guarantee that expected failures occur while the test is still running. We will need to add synchronization support in WebCore for appcache tests to be reliable. <rdar://problem/32256665>
