ACE_Asynch_Connector 的问题
在测试过程中，总是会出现这样的情况：1.创建一个socket
2.去closesocket这个socket
3.在去重新申请一个socket，这时新创建的socket就会提示：
ACE_Asynch_Connector::handle_connect : Set blocking mode: handle is not a socket
这是什么原因！？ 看具体代码才好分析。 谢谢，我解决了，不知道为什么在windows上面，因为先关闭一个socket，然后重新开启一个socket是前后执行的，如果连续执行就会有这个问题。
我现在改为需要close的socket等待5s后再closesocket（），这样就不会有问题了。 这个问题的核心是要保证closesocket调用的时候，所有异步事件都已经处理完了，否则是会出错的
等待5s就不出错，就是这个原因 thank you ! 我朋友一个新的问题，下面的log是在程序dump后打印出来的，大家看看什么问题哦！

No shared spaces configured. 而且我发现在acceptor执行ACE_Asynch_Write_Stream的write（）之后，在ACE_Asynch_Write_Stream_Result里面的complete（）参数里面的值突然的都没有了 我问下哦，如何socket关闭，并释放了资源的话，运行的程序的内存使用会降低啊！？
