Just a correction to the text above, there is no recursion, it is just a deep tree. As Dean says, you can have the same issue with a wide tree. We create the dependency tree immediately, so we should be able to scan how many filter primitives are in the tree and erase it if it has too many. Some operations probably should have a weight.
