 // Most consumers should only call GoogleURL(), which is guaranteed to
 // synchronously return a value at all times (even during startup or in unittest

 // the notification service for NOTIFY_GOOGLE_URL_UPDATED, and call GoogleURL()
 // again after receiving it, in order to get the updated value.
