If no 'response' handler is added, then the response will be entirely discarded. However, if a 'response' event handler is added, then the data from the response object must be consumed, either by calling response.read() whenever there is a 'readable' event, or by adding a 'data' handler, or by calling the .resume() method. Until the data is consumed, the 'end' event will not fire. Also, until the data is read it will consume memory that can eventually lead to a 'process out of memory' error.

这里可能是表明对于server和client的通信也有back pressure模式，所以如果对一个response添加了listener，那么就对其负责，而不消费就意味着对输出端不给释放的信号，从而导致server端内存溢出

提交commit的时候添加issues编号，能定位代码
