What?
The test is testing how constant arrival rate is starting iterations over time. But it used time.Sleep of 1 second which means that it doesn't actually check every second it checks and then it waits for 1 second and then again.
This seems to move enough, especially on windows, that it sometimes fails.
This PR uses time.Ticker to make it check every second, making it more likely that it won't drift.
Why?
Flaky test bad
