AFAIK, make-bytevector doesn't have an issue here, so by default I would assume mmap to not have it either, unless documented otherwise. However, I am not seeing tests or analysis that verify there's no issue here even though plausibly there might be an issue and neither am I seeing documentation that this doesn't work (for mmap in specific, or more generally).
