A thread.join exception coredump

```C++
        auto http_close_fn = [=]() {
            lt.hserver->Stop();
            OnListenThreadExited(exited_listen_thread_count->fetch_add(1) + 1);
        };
```

This lamba function use `=` to capture which will cause the shared_ptr<std::thread> copied and then we cannot determine when to destruct the thread.
