Why this should be merged
Since the state syncer can have multiple workers, there may be multiple in flight requests when it should start returning errors. Therefore, the number may be atomically increased more than twice.
For the other test, I haven't been able to replicate it locally. In order to see it flake (if it still does), I think we should remove it from the list of flakes
Closes #1357
