Hmm, I'm not sure whether this is a good idea. I mean, part of the aim of the test is to show that if you use the standard-issue urllib module, you do not get automatic protection against the endless data attack. However, if you just switch the module with a TUF interposition urllib replacement module, then you do get automatic protection. I think we should fix that underlying issue of why the interposition is not working for this test as expected. My intuition is that something has been misconfigured somewhere. Let's talk about this later.
