+ * area, the call to mutex_lock() will fail and terminate the
+ * afs process. This leads to dirty osl tables.
+ *
+ * There's no such problem with the other children of the
+ * server process (the command handlers) as these reset their
+ * SIGINT/SIGTERM handlers to the default action, i.e. these
+ * processes get killed immediately by the above kill().
