In a few days, I'll post a summary of how I think the PAM flow should go,
along with a patch to make that happen.  (I have to extract the patch from
my other local-isms.)  Solar Designer has at least some of the same
thoughts I did, but doesn't go "all the way".  (The Solar Designer
stuff made its way into 3.6.1p2 which is why folks are seeing this
change in behavior now.)
