内部动态创建的worker，onworkerstart没有输出

$worker = new Worker('text://0.0.0.0:2015');
$worker->onWorkerStart = function($worker)
{
    echo 'worker start';
    $taskWorker=new Worker('Text://0.0.0.0:12345');
    $taskWorker->onWorkerStart=function(){
        echo 'task start';
    };
    $taskWorker->listen();
};

// 运行worker
Worker::runAll();
