> This means that the _ConflictResolvingExternalResourceProviderWorker#poll_ is
> being called twice during the test instead on one time. The _poll_ is called
> only within the worker loop thus the worker is not stopped within time. This
> can happen when the test's main thread is slower than expected and allows the
> loop to have one more iteration.
> As a solution, the loop's waiting time is increased. This new value still
> does not make the tests slow or perventing them from properly running but
> significantly lowers the chance of having an extra iteration thus breaking
> the test.
