New submission from Philip Jenvey pjen...@underboss.org:
The __length_hint__ optimization was broken a while ago for many iterators due
to a bug introduced in 44c090c74202. It only accepts longs as valid hints, not
ints
This affects 2.6 too (but that's in security-only fix mode), but not 3.x

It's probably easier just to use PyNumber_Check.
