- Use a nonglobal asyncore socket map by default to hopefully prevent conflicts
  with apps and libs that use the asyncore global socket map ala
  https://github.com/Pylons/waitress/issues/63.  You can get the old
  use-global-socket-map behavior back by passing ``asyncore.socket_map`` to the
  ``create_server`` function as the ``map`` argument.

See #63
