Revert "bpo-36802: Drop awrite()/aclose(), support await write() and await close() instead (#13099)" by vstinner · Pull Request #13316 · python/cpython (original) (raw)

Without this change, python -m test test_asyncio -m test_drain_raises -v pass but logs a warning on my Windows VM:

test_drain_raises (test.test_asyncio.test_streams.StreamTests) ... Task exception was never retrieved

With this PR, it pass but doesn't log any warning.
