wasted some time because asyncio.wait_for() was suppressing cancellations. [0][1][2] deja vu... [3] Looks like this is finally getting fixed in cpython 3.12 [4] So far away... In attempt to avoid encountering this again, let's try using asyncio.timeout in 3.11, which is how upstream reimplemented wait_for in 3.12 [4], and aiorpcx.timeout_after in 3.8-3.10.
