Worker::stopAll()后代码无法更新问题

$worker->onClose = function($connection){
    echo '我都退出了你还不加载新代码!';
    Worker::stopAll();
};
$worker->onConnect = function($connection){
    // 设置连接的onMessage回调
    $connection->onMessage = function($connection, $data){
        require('./test.php');
        $connection->close();
    };
};
Worker::runAll();
