> dag.sub_dag(...) currently works by first deep copying the entire dag, and
> then filtering down to the appropriate tasks. that can be slow since deep
> copying a big dag takes a while. specifically, copying over all the tasks is
> the bottleneck
> this can be a lot faster by instead only copying over the filtered down tasks
