I don't have any memory of this patch. Arthur has since changed a bunch of how this works in CB:68160. I believe(?) that with his patch it shouldn't be possible to have a mapping window of size 0 anymore (although I'm not quite sure how it was previously possible to begin with). I think this patch is probably still valid as a sanity check but I don't think it should be possible to hit that case anymore.
