  -----------
  dsync: race condition where done/finish is received after one side has closed

We do not tell the remote we are closing if they have
already told us because they close the
connection after sending ITEM_FINISH or ITEM_DONE and will
not be ever receive anything else from us unless
it just happens to get combined into the same packet
as a previous response and is already in the buffer.
