To me, the surprise here is that usually you don’t expect Python finalizers to do something like this: when they dispose something, it’s usually unobservable from the perspective of the program, e.g. an unreachable file descriptor. Here, the runtime is disposing something that is still observably in progress, which is surprising behavior.
