+ * 1. Wait for "http-on-useragent-request" for the iframe load.
+ * 2. In the observer, access it's window proxy to trigger DOMWindowCreated.
+ * 3. In the event handler, delete the iframe so that the frameloader would be
+ * destoryed in the middle of ReallyStartLoading.
+ * 4. Verify that it doesn't crash.
