Well, I mean render engines wich don't have to parse the hole scene. It can 
do it in parts and when one part is rendered it will leave the pipe (and so 
it will free the memory). Don't know how they realize this but I read an 
article about that and they rendered test scenes with an astronomic number 
of verts or triangels.
