message:
  added code to ctdb to send a tcp 'tickle' ack when we takeover an
  IP. A raw tcp ack is sent for each tcp connection held by clients
  before the IP takeover.
  
  These acks have a deliberately incorrect sequence number, and should
  cause the windows client to send its own ack which will in turn cause
  a tcp reset and thus cause windows clients to much more quickly
  reconnect to the new node.
