I have fixed this using the attached patch.

Raymond, I would file a bug but trac won't let me register as a new
user. I'm cc-ing you because the comments in tmdb3.py indicate that you
are its author.

What the patch does is error out after a 30-second timeout, so that
tmdb3.py processes don't stall indefinitely.
