    @class Net::StdTcpServer

    A TcpServer opens a socket and listens for connecting TcpClients. This
    listen process happens in its own listener-thread and thus doesn't block
    the application. Each connected client is represented through a
    TcpClientConnection object which can be used by the application
    to communicate with a specific client.
