Review comment:
This is a subtle point. I might write something like "The worker waits for a
logical timer stream to be closed for every possible timer, regardless of
whether there are any timers to be sent."
Maybe it'd be clearer to iterate over `expected_output_timers`, and send
`fired_timers.get((transform_id, timer_family_id), [])`.
