 // Attempts to get the HEAD of a host name and displays an info bar if the
 // request was successful. This is used for single-word queries where we can't
 // tell if the entry was a search or an intranet hostname. The autocomplete bar
 // assumes it's a query and issues an AlternateNavURLFetcher to display a "did
 // you mean" infobar suggesting a navigation.
 //
 // The memory management of this object is a bit tricky. The location bar view
 // will create us and be responsible for us until we attach as an observer
 // after a pending load starts (it will delete us if this doesn't happen).
 // Once this pending load starts, we're responsible for deleting ourselves.
 // We'll do this in the following cases:
 //   * The tab is navigated again once we start listening (so the fetch is no
 //     longer useful)
 //   * The tab is closed before we show an infobar
 //   * The intranet fetch fails
 //   * None of the above apply, so we successfully show an infobar
