Actually, it doesn't lock up. It just looks like it locks up,
because it gets into a redirect loop: to the same URL!.
This is the sign of a broken web site. However, we should detect redirection
to the same URL (or redirect loops in general!)

More interestingly, the response is a 200 for the request that wget sends.
This is the Squeak dialog:
