    /// A `GThreadedSocketService` is a simple subclass of [`SocketService`][crate::SocketService]
    /// that handles incoming connections by creating a worker thread and
    /// dispatching the connection to it by emitting the
    /// [`run`][struct@crate::ThreadedSocketService#run] signal] in the new thread.
    ///
    /// The signal handler may perform blocking I/O and need not return
    /// until the connection is closed.
    ///
    /// The service is implemented using a thread pool, so there is a
    /// limited amount of threads available to serve incoming requests.
    /// The service automatically stops the [`SocketService`][crate::SocketService] from accepting
    /// new connections when all threads are busy.
    ///
    /// As with [`SocketService`][crate::SocketService], you may connect to
    /// [`run`][struct@crate::ThreadedSocketService#run], or subclass and override the default
    /// handler.
    ///
    /// ## Properties
    ///
    ///
    /// #### `max-threads`
    ///  The maximum number of threads handling clients for this service.
    ///
    /// Readable | Writeable | Construct Only
    /// <details><summary><h4>SocketService</h4></summary>
    ///
    ///
    /// #### `active`
    ///  Whether the service is currently accepting connections.
    ///
    /// Readable | Writeable | Construct
    /// </details>
    /// <details><summary><h4>SocketListener</h4></summary>
    ///
    ///
    /// #### `listen-backlog`
    ///  The number of outstanding connections in the listen queue.
    ///
    /// Readable | Writeable | Construct
    /// </details>
    ///
    /// ## Signals
    ///
    ///
    /// #### `run`
    ///  The ::run signal is emitted in a worker thread in response to an
    /// incoming connection. This thread is dedicated to handling
    /// @connection and may perform blocking IO. The signal handler need
    /// not return until the connection is closed.
    ///
    ///
    /// <details><summary><h4>SocketService</h4></summary>
    ///
    ///
    /// #### `incoming`
    ///  The ::incoming signal is emitted when a new incoming connection
    /// to @service needs to be handled. The handler must initiate the
    /// handling of @connection, but may not block; in essence,
    /// asynchronous operations must be used.
    ///
    /// @connection will be unreffed once the signal handler returns,
    /// so you need to ref it yourself if you are planning to use it.
    ///
    ///
    /// </details>
    /// <details><summary><h4>SocketListener</h4></summary>
    ///
    ///
    /// #### `event`
    ///  Emitted when @listener's activity on @socket changes state.
    /// Note that when @listener is used to listen on both IPv4 and
    /// IPv6, a separate set of signals will be emitted for each, and
    /// the order they happen in is undefined.
