-// This class forwards events to ExtensionEventRouters.
-// The advantages of this class over direct usage of ExtensionEventRouters are:
-// - this class is thread-safe, you can call the functions from UI and IO
-//   thread.
-// - the class can handle if a profile is deleted between the time of sending
-//   the event from the IO thread to the UI thread.
-// - this class can be used in contexts that are not governed by a profile, e.g.
-//   by system URLRequestContexts. In these cases the |restrict_to_profile|
-//   parameter remains NULL and events are broadcasted to all profiles.
