Yeah, I agree that passing fds is pretty painful to implement and look
at.

Do you mean having single dmmap AS is okay?

And then the above seems contradictory with the first sentence. Sorry
to be dense but I really don't follow what you're suggesting. If
you're okay with single dmmap AS, how can you not be okay with the
quirks of dealing with global AS? The only exit from that problem is
having multiple ASes.
Thanks.
