/** Make it easy to implement a network service.
 *
 * @see ThreadedSocketService, SocketListener.
 *
 * A %SocketService is an object that represents a service that is
 * provided to the network or over local sockets.  When a new
 * connection is made to the service signal_incoming() is emitted.
 *
 * A %SocketService is a subclass of SocketListener and you need
 * to add the addresses you want to accept connections on with the
 * SocketListener APIs.
 *
 * There are two options for implementing a network service based on
 * %SocketService. The first is to create the service using
 * create() and to connect to signal_incoming().
 * The second is to subclass %SocketService and override the
 * default signal handler implementation, on_incoming().
 *
 * In either case, the handler must immediately return, or else it
 * will block additional incoming connections from being serviced.
 * If you are interested in writing connection handlers that contain
 * blocking code then see ThreadedSocketService.
 *
 * The socket service runs on the main loop of the thread-default context
 * of the thread it is created in, and is not
 * threadsafe in general. However, the calls to start and stop
 * the service are threadsafe so these can be used from threads that
 * handle incoming clients.
