message:
  Fix for Bug#38992: Server crashes sporadically with
  'waiting for initial ...' msg on windows.
  
  The problem is that connection timeout is too small
  for busy windows box.
  
  The fix is to
    - add support for connect_timeout command line argument
      to mysqltest;
    - set default value of the connect_timeout option to
      120 seconds.
