Ok, when I say "no sharing" I mean of mutable data, which is where all
the problems you and everyone else have mentioned come from.
I have mentioned several times in this thread that classes and code
*are a concern*. But I think a solvable one. Doing things to classes
(e.g. creating, renaming, adding methods, removing methods, changing
methods) are a special case now, and they will be a special case in my
proposed system as well. Note that Erlang has this same issue and
they solved it in their case 10 years ago. I think this is a solvable
problem.

As mentioned in probably no less then 10 other emails: I think the
"ObsoleteClass" mechanism will be workable for this.
