Clever.

I think your ABI extension is a good one, and I don't see any reason
not to include it.  If there aren't any objections in the next week,
I'll include it.  (I've put a sticky on my virtual calendar to
remind me.)

I guess we should make this optional, in the same sense as the
priority stuff is optional -- if you implement this, this is what
you should do, but if you're trying to write code portable across
ABI implementations, you should not depend on this being present.

Do you agree?
