> The reason is a query cancellation that acquires an iterator's lock to check
> the availability of a next row and thus update a state of the cursor to
> prevent unnecessary request cancelation. But the lock is already held by a
> query thread to fetch a next page, so the cancellation is forced to wait till
> the page will be completely prefetched.
