Oh, right.  But:

1) Neil's scheme does not replace reference counting.
2) There are more things between the status quo and a free threaded
   interpreter than reference counting issues.

So the answer to your question is: "no".


  well, take it from an old hand: the only reason it would be easier
  to program in C is that you can't easily express complex  problems
  in C, so you don't.                   -- Erik Naggum, comp.lang.lisp
