      Description

      The SEQUENCER protocol ensures that the messages that are not acked by the previous coordinator are forwarded to the new coordinator. This ensures reliable transmission of data. It will be better to have a way to turn off this behavior. I.e. when a coord change has occurred, drop all the messages in the forward table.

      Background:
      A network partition can cause data inconsistencies if both sub-groups continue to support updates. I do not want to continue processing on the sub-group that has lost its coord (or continue transmission with the new coord of the un-acked data).
