> h3. Implementation notes
> The test became flaky after IGNITE-21290. The reason is that the cursors of
> the scan operations are closed asynchronously, but the test checks that they
> are closed immediately after the Subscription#cancel() method is invoked.
> If the test takes several milliseconds, the cursors will be clearly closed.
> {code}
> waitForCondition(() -> storage.pendingCursors() == 0, 10_000)
> {code}
