Streaming templating languages for use as WSGI body.

Howdy!
I'm trying to find a templating engine whose templates can be consumed 
directly as a WSGI response body iterable. So far I haven't been very 
successful with Google; the engines I've found universally generate a 
monolithic rendered string.
Bonus points for templating engines that support flush() mechanics 
internally to allow developer-chosen 'break points' in the iterable. 
Bonus points++ if it can somehow calculate the response body length 
without generating the whole thing monolithically. ;)
