>
> After a BlockReceiver finish receiving the last packet of a block, it waits
> until the ack queue becomes empty. It them assumes that all acks have been
> sent and shunts down network connections. The current code removes a packet
> from the ack queue before its ack is sent. So there is a chance that the
> connection gets closed before an ack is sent.
