Maybe we are ok with this behavior as I haven't dug deep enough into the memory
subsystem here to really understand what the memory code is updating, but it is
concerning that we are doing it in some cases, but not all.

I hope I've made a good case above that the notifier does not do any
useful work, and a counterpart for the v2 format isn't needed.  Do you
agree?

If so, I'll send a patch later to remove the notifier altogether. In the
near term I would still like this minimal fix to go in.

Tyrel, ack?

Sure, lets start with simple case to fix the crash.
