Update to 1.09:

v1.09
        - new method stop_SSL as opposite of start_SSL based on a idea
          of Bron Gondwana <brong[AT]fastmail[DOT]fm>
          To support this method the SSL_shutdown handling had to be
          fixed, e.g. in close a proper unidirectional shutdown
          should be done while in stop_SSL a bidirectional shutdown
        - try to make it clearer that thread support is buggy
