* add loseWriteConnection() method * add async_write() that does not wait (synonim for transport.write()) * GreenTransport's protocols now required to implement IHalfClosable interface * GreenTransport use PullProducer instead of PushProducer * add test for loseWriteConnection and remove test that does not work anymore
