+ * This class can also be used, without notification, just to get key values from
+ * central repository.
+ * To make it start listening on a specific key value change, create an instance of
+ * this class using the argumented NewL/NewLC functions.
+ * A request can only be cancelled, when the object of this class
+ * is deleted.
