> "If the operations we are talking about are ordered, then this provides the atomicity that TFA is asking for." No, it doesn't. I think we're reaching the heart of the disagreement here - around what "atomic" means. Atomic means indivisible. It means that other things cannot happen at the same time - that the individual (possibly ordered) steps of an operation cannot be observed while in progress. This is why it's absolutely nonsense to talk about atomicity across a crash. The fundamental design of unix files and memory preclude this. It can't be done.
