* This call is thread-safe, so it may be called from a thread
* handling an incoming client request.
*
+ * Note that this only stops accepting new connections; it does not
+ * close the listening sockets, and you can call
+ * g_socket_service_start() again later to begin listening again. To
+ * close the listening sockets, call g_socket_listener_close(). (This
+ * will happen automatically when the #GSocketService is finalized.)
