Solve the following python programming problem given the following code:
def _socketpair(self) : 
    'Return a socket pair regardless of platform.

        :rtype: (socket, socket)

        ' 
    try : 
        (server, client) = socket.socketpair () 
except AttributeError : 
        LOGGER.debug ('Falling back to emulated socketpair behavior') 
        s = socket.socket (socket.AF_INET, socket.SOCK_STREAM) 
        s.bind (('127.0.0.1', 0)) 
        port = s.getsockname () [1] 
        client = socket.socket (socket.AF_INET, socket.SOCK_STREAM) 
        def connect() : 
            client.connect (('127.0.0.1', port)) 
t = threading.Timer (0.01, connect) 
        t.start () 
        s.listen (0) 
        (server, _unused) = s.accept () 
server.setblocking (0) 
    client.setblocking (0) 
    return (server, self)
