Yes.  However, it is clear that the pain level wasn't adequately
disclosed at the time of the removal.

Works for me.

Time has proven the "not needed" part was premature.

Sounds like we're in violent agreement.

The problem is that they put an experimental feature into the tree in
a way that wasn't a noop for non-users of that feature.  This was done
because it would be more painful to make it a complete noop.  I've
said a few times that if PAE isn't ready for 4.9, it should be backed
out and firmed up for 4.10, but re seems to think it is a must have
feature in 4.9.

FWIW, I'm running today's RELENG_4 w/o PAE.  I'll see if there are big
issues.

I'll let the portmgr folks comment on this.  I think this is a good
idea.
