- * This thread manage application communication.

+ * or an error occurs.
+ *
+ * At that point, it flushes the data (tracing and metadata) associated
+ * with this application and tears down ust app sessions and other
+ * associated data structures through ust_app_unregister().
+ *
+ * Note that this thread never sends commands to the applications
+ * through the command sockets; it merely listens for hang-ups
+ * and errors on those sockets and cleans-up as they occur.
