Description of Changes

Please describe your change, mention any related tickets, and so on here.

  • Fixes an issue where the reducer queue metric wouldn't get decremented, which would leave a baseline count which would never reach 0 even if the queue was empty.

Expected complexity level and risk

How complicated do you think these changes are? Grade on a scale from 1 to 5,
where 1 is a trivial change, and 5 is a deep-reaching and complex change.

This complexity rating applies not only to the complexity apparent in the diff,
but also to its interactions with existing and future code.

If you answered more than a 2, explain what is complex about the PR,
and what other components it interacts with in potentially concerning ways.

I might wrap this in a scope guard to future proof. At the very least I would add a comment about decrementing in the case of a semaphore closure.
