Note that he said that the *finally* clause were useless (and I'd say so,
too), not the *except* clause.
And yes, in Python it is checked - when the close method was called
explicitely, an exception is raised; when called when the object is garbage
collected, a message is printed on sys.stderr

Only supresses the message on sys.stderr - exceptions raised on __del__ are
never propagated.
