> The abstraction of AbstractAsyncIOCallable does not fit to well with todays needs in checkpointing backends. Originally, backends were assumed to only open one stream that is managed by the abstraction. In fact, concrete implementations always extended that in practise. We can redo this in a way that more resources can be managed by the abstraction.
