I am going to guess that you can actually run code  in the interpreter
here. When printing from threads, the prompt will end up in the wrong place
as the prompt is printed in the main thread. Similarly, there is a (decent)
chance that the prints will be done out-of-order (multiple "<Thread..."
lines or URLs next to each other or on the same line). The odds that such
behavior will occur will increase as the work become more complex and more
threads are created. All of this can be resolved by manually using the
locking provided in the threading module.
