Solve the following python programming problem given the following code:
@ asyncio.coroutine 
def run_as_coroutine(self, stdin, callbacks) : 
    "
        The input 'event loop'.
        " 
    assert isinstance (callbacks, EventLoopCallbacks) 
    stdin_reader = PosixStdinReader (stdin.fileno ()) 
    if self.closed : 
        raise Exception ('Event loop already closed.') 
inputstream = InputStream (callbacks.feed_key) 
    try : 
        self._stopped_f = asyncio.Future () 
        def timeout_handler() : 
            '
                When no input has been received for INPUT_TIMEOUT seconds,
                flush the input stream and fire the timeout event.
                ' 
            inputstream.flush () 
            callbacks.input_timeout () 
timeout = AsyncioTimeout (INPUT_TIMEOUT, timeout_handler, self.loop) 
        def received_winch() : 
            self.call_from_executor (callbacks.terminal_size_changed) 
self.loop.add_signal_handler (signal.SIGWINCH, received_winch) 
        def stdin_ready() : 
            data = stdin_reader.read () 
            inputstream.feed (data) 
            timeout.reset () 
            if stdin_reader.closed : 
                self.stop () 
self.loop.add_reader (stdin.fileno (), stdin_ready) 
        for f in callbacks._stopped_f : 
            (yield f) 
finally : 
        self.loop.remove_reader (stdin.fileno ()) 
        self.loop.remove_signal_handler (signal.SIGWINCH) 
        timeout.stop ()
