Leaks?

I'm using smarty in our mailing list management system, and I'm  
running into some memory issues. Unlike a typical web template  
scenario where smarty renders a template just once, I typically  
render a set of 3 related templates around 1000 times with different  
assigned vars. To reduce instantiation overhead, I'm keeping the  
smarty instance in a static var and clearing its contents in each  
iteration.

Something in my loop is eating memory and not giving it back. Memory  
is being eaten at a rate of about 10k per iteration, which is about  
the size of the rendered templates. I've eliminated my database as  
the source. Has anyone noticed Smarty doing this? Is there anything  
particular that smarty might be storing and then not releasing?
