+ * Implementation of EVEL functions relating to the internal events.
+ *
+ * Internal events are never expected to be sent to the JSON API but comply
+ * with interfaces for regular event types. The primary use-case is to enable
+ * the foreground processing to communicate with the background event handling
+ * processing in an orderly fashion. At present the only use is to initiate an
+ * orderly shutdown of the Event Handler thread.
