Our point of view was:

* we have a mixed language, multi-process program

* we need parts of it to run with priorities higher than those of
  normal processes

* we can use priocntl to get this to happen (this was Solaris)

* wow! if we run as root, GNAT does what we want! (this was 3.11, I
  think)

so the question of whether we had Annex D dispatching rules never
entered our heads.

We were delighted to have found a solution, so never raised the
question with ACT. Had we still been supported on that contract when
we discovered the changed behaviour, we would of course have asked!
