最近在做一个采集系统时，发现协程http客户端，在服务器完全断网，请求失败后不会立即退出

最近在做一个采集系统时，发现协程http客户端，在服务器完全断网(不是DNS失效,直接断网)，请求失败后不会立即退出，这样导致进程还在占用部分资源，当我的服务器繁忙的时候，直接导致服务器内存耗干了。正常网络或者DNS失效这种情况是正常退出的

php 版本:7.2

```php
php --ri swoole

swoole

使用的是官方的例子

Co\run(function () {
        $client = new Swoole\Coroutine\Http\Client('127.0.0.1', 80);
        $client->setHeaders([
            'Host' => 'localhost',
            'User-Agent' => 'Chrome/49.0.2587.3',
            'Accept' => 'text/html,application/xhtml+xml,application/xml',
            'Accept-Encoding' => 'gzip',
        ]);
        $client->get('/index.php');
        echo $client->body;
        $client->close();
    });
