39  * A #GThreadedSocketService is a simple subclass of #GSocketService
40  * that handles incoming connections by creating a worker thread and
41  * dispatching the connection to it by emitting the
42  * #GThreadedSocketService::run signal in the new thread.
43  * 
44  * The signal handler may perform blocking IO and need not return
45  * until the connection is closed.
46  * 
47  * The service is implemented using a thread pool, so there is a
48  * limited amount of threads available to serve incoming requests.
49  * The service automatically stops the #GSocketService from accepting
50  * new connections when all threads are busy.
51  * 
52  * As with #GSocketService, you may connect to #GThreadedSocketService::run,
53  * or subclass and override the default handler.
54  *
55  * Since: 2.22
