Segfault in uvloop 0.22.1

Chưa có ai nhận issue này.

Hi, I see a sefault in uviloop in my fastapi app. I can reproduce it 100% of the time inside the container.

The app is run with

```bash
python -X faulthandler -m uvicorn --loop uvloop app:app
```

If I switch to `--loop asyncio` I do not get a segfault.

```
Fatal Python error: Segmentation fault

I wasn't able to get a coredump because I don't have access but could possibly get one if required.

Bắt đầu bằng cách tái hiện crash với Python 3.12.12, uvloop 0.22.1 và `python -X faulthandler -m uvicorn --loop uvloop app:app`, sau đó so sánh với `--loop asyncio`. Thu hẹp môi trường và lấy coredump nếu có thể; công việc được xem là hoàn tất khi xác định được nguyên nhân liên quan đến uvloop và xác minh rằng cùng ứng dụng đó không còn bị segfault.

Do mô hình lập chỉ mục viết ra từ nội dung của issue.
