I did consider this model.  I even floated the idea on this list, though
as I recall nobody replied.

One thing worth noting is that you can experiment with this approach
right now.  I haven't tried but I think you can do it purely in elisp
with no emacs changes required.

Give it a try.  If it is a better model, well, great, let's use it.

That is true, but due to the nature of actually existing Emacs code I
don't think it will be a problem in practice.

Also: (1) this cannot happen with let-bound variables, only globals; and
(2) this can already happen today via process filters (in limited
scenarios, to be sure -- but the threading is cooperative, so the same
applies).
