> Robert Newson commented on the user@ list: "Pretty obvious bug, yes. We're attempting
to evaluate whether the atom 'chunked' is greater than zero."
> The obvious workaround -- don't use chunked -- may not be available to clients. This
level of encoding is generally performed by the browser or client HTTP library, and the app
level code may not have control over whether it's performed.
