I would say that vital cleanup code probably shouldn't do
anything that could block. If you really need to do that,
it should be protected by a finally clause of its own:

    def foo():
        connection = open_connection()
        try:
            spam()
        finally:
            try:
                [some code]
            finally:
                connection.close()
