Yes, it looks strange - but it is the best option I have found so far.
I've seen tests fail a few times in CI due to race.
More details are available at [0] and particularly [1].
In a few words - it is an attempt to make sure the test goes to the
wake-up backend only after it actually enters to wait mode. For that
reason an additional 'notice' point is used by spec.
I have proposed another possible solution for the [0] thread.
Best regards,
Mikhail.
