is a reasonable thing to do. The seq_file code will also avoid taking any
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
+it often will be.
