  SVN rev 220678 on 2011-04-15 20:42:14Z by jhb
  
  MFC 220156:
  Clamp the initial advertised receive window when responding to a SYN/ACK
  to the maximum allowed window.  Growing the window too large would cause
  an underflow in the calculations in tcp_output() to decide if a window
  update should be sent which would prevent the persist timer from being
  started if data was pending and the other end of the connection advertised
  an initial window size of 0.
