锁定代码块：

threadLock = threading.Lock()threadLock.acquire()# somecode...threadLock.release()

阻塞直到线程结束：

thread1 = myThread(1, "Thread-1", 1)thread2 = myThread(2, "Thread-2", 2)thread1.start()thread2.start() # 添加线程到线程列表threads.append(thread1)threads.append(thread2) # 等待所有线程完成for t in threads:    t.join()print "Exiting Main Thread"

join([time])方法: 等待至线程中止。

这阻塞调用线程直至线程的join()方法被调用中止：

• 正常退出
• 抛出未处理的异常
• 可选的超时发生。
