> Running the TestPread with additional debug statements reveals that the BlockReader sends CHECKSUM_OK when the DataXceiver doesn't expect it. Currently it doesn't matter since DataXceiver closes the connection after each op, and CHECKSUM_OK is the last thing on the wire. But if we want to cache connections, they need to agree on the exchange of CHECKSUM_OK.
