The only immediate goal is to be able to get this bit logic out of
bind_to_vm, so I can use "preallocated" nodes a bit more cleanly. At
least for the present, I have no plans with it other than that. I did
like the resuse of the PDE allocation for gen7.

If I think of a better reason, I'll let you know.
