今天在学习muduo中的EventLoop类，代码如下：

#include <errno.h>                                                 
#include "muduo/net/EventLoop.h"                                                                                                                                                            
#include <thread>                                                  
                                                                   
int main()                                                         
{
                                                                     
    muduo::net::EventLoop testloop;                                
    testloop.loop();                                               
    return 0;                                                      
}

以一个案例做实验的时候出现了如下问题：
