+	If the clone flag is set, then a duplicated message, with larger payload
+	size, is allocated and returned.  The old_msg pointer in this situation is
+	still valid and must be explicitly freed by the application. If the clone 
+	message is not set (0), then any memory management of the old message is
+	handled by the function.
