I'm not saying it's a perfect analogy, but in POSIX you absolutely can expect the file to be unlinked regardless of what order and timing they were dispatched in.

In this case what we have is a delete operation that reports success but never resulted in the file never actually being gone. That seems different to me than having conflicting writes where one of them is never user-visible, somehow. I'd like somebody else to weigh in on it.
