- IFC: use smart pointers to keep STEP-SELECT entities in the converted output data structures. This allows us to free the original parameter tuples early as ownership of their members can be transferred. This cuts down memory overhead to 8x (assuming a typical x64 builds) and reduces loading time on average by ~5% as measured on my system.
