The only times I've heard of oconv getting stuck and using up memory is 
when there are many overlapping instances, or if many polygons come 
together at a single vertex, when it tries to resolve this down to the 
finest level.  Otherwise, it should work -- especially with such a 
small model.  If you send me one of these models, I'd love to have a 
look to see what's going on.
