37 /**
38  * A #GThreadedSocketService is a simple subclass of #GSocketService
39  * that handles incoming connections by creating a worker thread and
40  * dispatching the connection to it by emitting the
41  * #GThreadedSocketService::run signal in the new thread.
42  * 
43  * The signal handler may perform blocking IO and need not return
44  * until the connection is closed.
45  * 
46  * The service is implemented using a thread pool, so there is a
47  * limited amount of threads available to serve incoming requests.
48  * The service automatically stops the #GSocketService from accepting
49  * new connections when all threads are busy.
50  * 
51  * As with #GSocketService, you may connect to #GThreadedSocketService::run,
52  * or subclass and override the default handler.
53  *
54  * Since: 2.22
