Comment (by Andrew Godwin):
Hmm yes, this is one of those nasty bugs that reveals the true nature of
how Python async works.
In testing this locally with just plain async functions, I don't see how
we can catch this - the error happens when you return StopIteration from
_any_ awaited function, you can't wrap around it to catch it instead.
Given that views are always going to be async functions, unless we want to
wrap every single view, decorator and middleware in our own custom Future
it's not going to be reasonable to catch it.
