Solve the following python programming problem given the following code:
@ testing.requires.threading_with_mock 
@ testing.requires.timing_intensive 
def test_waiters_handled(self) : 
    'test that threads waiting for connections are
        handled when the pool is replaced.

        ' 
    mutex = threading.Lock () 
    dbapi = MockDBAPI () 
    def creator() : 
        mutex.acquire () 
        try : 
            return dbapi.connect () 
finally : 
            mutex.release () 
success = [] 
    for timeout in (None, 30) : 
        for max_overflow in (0, (- 1), 3) : 
            p = pool.QueuePool (creator = creator, pool_size = 2, timeout = timeout, max_overflow = max_overflow) 
            def waiter(p, timeout, max_overflow) : 
                success_key = (timeout, max_overflow) 
                conn = p.connect () 
                success.append (success_key) 
                time.sleep (0.1) 
                conn.close () 
c1 = p.connect () 
            c2 = p.connect () 
            threads = [] 
            for i in range (2) : 
                t = threading.Thread (target = success, args = (p, timeout, max_overflow)) 
                t.daemon = True 
                t.start () 
                threads.append (t) 
time.sleep (0.2) 
            p._invalidate (c2) 
            for t in threads : 
                t.join (join_timeout) 
eq_ (len (success), 12, ('successes: %s' % success)) 

    
    

    Fix the buggy line: t = threading.Thread (target = success, args = (p, timeout, max_overflow))

#Here is Python program to fix the buggy line: t = threading.

t = threading.Thread (target = def waiter(, args = (p, timeout, max_overflow))
