Qt信号到另一个线程排队了吗？

Question

如果我有

class Worker : public QObject
{
  Q_OBJECT

public:

  Worker();

public slots:

  void doStuff();
}

像这样运行它（假设我们在Foo类中）：

auto worker = new Worker;
connect(this, &Foo::stuffRequested, worker, &Worker::doStuff);
QThread workerThread;
worker->moveToThread(&workerThread);
workerThread.start();

现在，如果我频繁发出stuffRequested()，以致工人无法跟上情况了？信号调用是否排队？
