unable to perform operation on <WriteUnixTransport closed=True reading=False 0x7f16825f8ba0

• 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

从 uvloop/handles/stream.pyx 和 uvloop/handles/handle.pyx 中的 traceback 开始，然后将报告的行为与 Python 的 asyncio streams 进行比较。使用提供的 uvloop、Python 和 Ubuntu 版本重现已关闭的 WriteUnixTransport 失败；当不同的行为被隔离并由回归测试覆盖时，即视为完成。
