+        Add lock profiling tool.</p>
+          <p>
+        The Lock profiling tool, lcnt, can make use of the
+        internal lock statistics when the runtime system is built
+        with this feature enabled.</p>
+          <p>
+        This provides a mechanism to examine potential lock
+        bottlenecks within the runtime itself.</p>
+          <p>
+        - Add erts_debug:lock_counters({copy_save, bool()}). This
+        option enables or disables statistics saving for
+        destroyed processes and ets-tables. Enabling this might
+        consume a lot of memory.</p>
+          <p>
+        - Add id-numbering for lock classes which is otherwise
+        undefined.</p>

+        emacs: Moved code skeletons to a separate file and and
+        added a configurable variable to choose skeleton. Thanks
