If RenderFrameImpl::willSendRequest cancels the load,
m_resource->willSendRequest() might now do something crazy. I can't find any
evidence that it ever does cancel, though. Do you know for sure?

     m_resource->willSendRequest(request, redirectResponse);
     if (request.isNull() || m_state == Terminated)
         return;

     request.setReportLoadTiming(true);
     ASSERT(!request.isNull());
