Ok, then that is really not sufficient. I apparently got a mistaken
impression of how early it gets called from the previous discussion. The
more I think about it, the more a single new hook that is clearly "inferior
address space we haven't seen before" (i.e. exec/attach but not fork) looks
like the clean and sensible thing. All the existing hooks have semantics
that are either not quite clear or are clearly different from that.
