* **uvloop version**: 0.17.0
* **Python version**: 3.10.7
* **Platform**: ubuntu 20.04
* **Can you reproduce the bug with `PYTHONASYNCIODEBUG` in env?**: yes
* **Does uvloop behave differently from vanilla asyncio? How?**: yes

uvloop/handles/stream.pyx と uvloop/handles/handle.pyx の traceback から始め、その後、報告された動作を Python の asyncio streams と比較します。提供された uvloop、Python、Ubuntu のバージョンを使って、閉じた WriteUnixTransport の失敗を再現します。異なる動作を切り分け、回帰テストでカバーできれば完了です。
