Solve the following python programming problem given the following code:
@ pytest.fixture (scope = 'module') 
def server(request) : 
    p1 = TProcessor (mux.ThingOneService, DispatcherOne ()) 
    p2 = TProcessor (mux.ThingTwoService, DispatcherTwo ()) 
    mux_proc = TMultiplexedProcessor () 
    mux_proc.register_processor ('ThingOneService', p1) 
    mux_proc.register_processor ('ThingTwoService', p2) 
    _server = TThreadedServer (mux_proc, TServerSocket (unix_socket = sock_path), iprot_factory = TBinaryProtocolFactory (), itrans_factory = TBufferedTransportFactory ()) 
    ps = multiprocessing.Process (target = _server.serve) 
    ps.start () 
    time.sleep (0.1) 
    def fin() : 
        if ps.is_alive () : 
            ps.terminate () 
try : 
            os.remove (sock_path) 
except IOError : 
            pass 
request.addfinalizer (p2) 

    
    

    Fix the buggy line: request.addfinalizer (p2)
