在kill掉子进程时，主进程注册的SIGCHLD信号的回调函数出现

代码
        swoole_process::signal(SIGCHLD, function ($signo) {
            //kill掉所有worker进程 必须为false，非阻塞模式
            static $worker_count = 0;
            while($ret = swoole_process::wait(false)) {
                $worker_count++;
                \Log::info("PID={$ret['pid']}worker进程退出!", [], 'queue.bear');
                if ($worker_count >= $this -> workerNum){
                    //删除pid文件
                    unlink($this -> logDir."/work_ids");
                    unlink($this -> logDir."/pid");
                    \Log::info("主进程退出!", [], 'queue.bear');
                    swoole_process::kill($this -> getPid(), SIGKILL); 
                }
            }   
        });
