重新学习python线程应用使用thread类，改写程序

1. #!/usr/bin/envpython
2. #-*-coding:cp936-*-
3. #===============================================================================
4. #1、将原程序改为多线程
5. #2、加入线程之间的互斥和锁操作
6. #3、当其中一个线程执行完成后通知锁对象将该线程释放
7. #===============================================================================
