+/* The following functions will support advanced output module
+ * multithreading, once this is implemented. Currently, we
+ * include them as hooks only. The idea is that we need to guard
+ * some msg objects data fields against concurrent access if
+ * we run on multiple threads. Please note that in any case this
+ * is not necessary for calls from INPUT modules, because they
+ * construct the message object and do this serially. Only when
+ * the message is in the processing queue, multiple threads may
+ * access a single object.
