编译应该没问题，运行的时候可能会有错误：error while loading shared libraries: libZThread-2.3.so.2: cannot open shared object file: No such file or directory
把 libZThread-2.3.so.2? cp 到/usr/lib目录应该就可以运行了。
运行结果如下：
=============================================================

运行的结果不一定跟上面的结果完全一致，这正是多线程程序的特点:)
对于ZThread库和多线程编程的入门级介绍，请参阅Thinking in C++第二卷，如果已经对此熟练掌握，可以看看Parallel and Distributed Programming Using C++，这本书不仅提供了一些优秀的多线程库的介绍，更重要的是一些多线程编程思想的介绍和理解，值得一读。
