 // This test is broken because ResourceLoader assumes when
 // URLRequest::was_pending() is false, canceling the request will not result in
 // a completion notification.  This isn't the case - whether or not there's a
 // notification depends on whether URLRequestJob::NotifyDone() has been invoked
 // yet - something the URLRequest doesn't even know about, itself. As a result,
 // the ResourceLoader is notified of cancellation twice.
 // TODO(mmenke): Fix this.
