But did you spot the bug(s)?
My itertools-based version would look like this

    def get_tweets(term):
        pages = (api.GetSearch(term, pageno)
                 for pageno in itertools.count(1))
        for page in itertools.takewhile(bool, pages):
            yield from page

but I can understand that it's not everybody's cup of tea.
