      Description

      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.
