Object::Subtreeon its command only, so reading its owninput walks up from the object. The proof is one hop long but many other
packages reference that input. The walk enumerates every parent it has
accumulated, so the read gets slower as the store grows.
Reading the same file 200 times costs 0.26s with no other parents and 2.48s
once 640 unrelated packages depend on it.
