Thanks for flagging that @valery1707! 🙌

I looked into the test, and found why it's flaky. I restarted the build so we can merge your fix, I didn't want to just restart and merge without investigating first 😅

The test relies on delay(resetTimeout + 10.milliseconds), as a condition for the CircuitBreaker to recover.. which is of course not great for a test.
I think we can safely ignore it for now, CircuitBreaker is up for an update for Arrow 2.0 anyway. We want to build a proper resilience library where this will be included. We can do a rehaul the tests there to remove relying on delay.
