I find it extremely scary to read this sort of blue-sky design
discussion going on now, two months after we were supposedly
feature-frozen for 9.0.  We need to be looking for the *rock bottom
minimum* amount of work to do to get 9.0 out the door in a usable
state; not what would be nice to have later on.
