 other locks while the iterator is active.
 
+The iterater value returned by start() or next() is guaranteed to be
+passed to a subsequent next() or stop() call.  This allows resources
+such as locks that were taken to be reliably released.  There is *no*
+guarantee that the iterator will be passed to show(), though in practice
