and the next step on from this is to realise that the problem isn't how to
code the calls to get_request(), the problem is actually that get_request()
itself isn'ty Pythonic. Rewrite it as a generator, rename it to reflect
that it now generates a sequence of requests and the code becomes:
for rq in incoming_requests(...):
handle_request(rq)
