SQLAlchemy driver does not clean up expired messages

[Kurt Griffiths]

The code for this needs to go into MessageController.post

[peng fei wang (wpf)]

I saw that code was already there but commented

            # cleanup all expired messages in this queue
            #self.driver.run('''
            # delete from Messages
            # where ttl <= julianday() * 86400.0 - created
            # and qid = ?''', qid)

is that Ok?
