"""
Regression test: exec_bash_command must actually catch the timeout raised
by asyncio.wait_for.

`from redis.asyncio import ... TimeoutError` used to shadow the builtin, so
`except TimeoutError` never matched asyncio's builtin TimeoutError. Timed-out
commands fell through to the generic handler, the child process was never
terminated, and the caller got a misleading "unable to execute" error.
