> 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.
