    Thanks !!! it works fine.
    question: upon calling GzipConsumer's close methos, it in turn invokes a
    consumer close method, too.
    on the stupid_consumer you demonstrated there is no such method. the
    question is whether an extremely_stupid
    "def close(self): pass" method is just fine or is there something important
    to do with the data ?
