> {{BPServiceActor#pendingReceivedRequests}} is not tracked correctly for
> multiple storages. Previously this counter was treated more like a flag, i.e.
> we only cared whether it was zero or not. With multiple storages we need to
> be more precise in tracking this value to correctly determine when to
> generate incremental block reports.
