Logically, it's sound, but the implementation will be very difficult.  I also

As far as I can tell, the ref counting proposal is not viable without it, as 
long as you insist on non-atomic RC increments and decrements.  How can it 
possibly not be a prerequisite to this, and therefore part of the proposal?

Unless you are saying now that atomic ref counting is OK?

I'm going by your previous statement:
