I can't help feeling that this is basically a sign the fetcher is
broken.
What should really happen here is that there should be a method in the
fetcher we call into.
Instead we're teaching code how to hack around the fetcher. Would it be
possible to add some API we could call into here and maintain integrity
of the fetcher API?
Cheers,
Richard
