It should return a false value if normal iteration should be used instead. An exception can be raised to indicate that transmission was attempted, but failed.

It's also the base class for CGIHandler, which just uses sys.stdin, os.environ, and so on. The constructor also takes keyword arguments 'multithread' and 'multiprocess' (defaulting to 'True' and 'False' respectively) to control the configuration sent to the application. It sets 'origin_server' to False (to enable CGI-like output), and assumes that 'wsgi.run_once' is False.

It does not take any initialization parameters, but always uses 'sys.stdin', 'os.environ', and friends.
