short version, nestled snuggly in django.template.defaulttags.ForNode.render is a homebrewed native reverse implementation; aside from it using range when it should be using xrange, this is fine for <py2.4; for >=py2.4 however, the builtin reversed should be used (fair bit faster among other things).
So... attached is a patch doing just that; for folks using >=2.4, it's a linear 10x boost (mass index lookups kill kittens when in combination with native py vs cpy speeds), so... worth adding.
