Follow-up Comment #16, bug #44330 (project octave):

My understanding is that the atomic refcount thing ensures that refcounting is
done properly when those objects are copied across threads.

But there are other things that can cause trouble.  For example, you can't ask
the interpreter to evaluate a function at an arbitarary time because it could
be busy evaluating some other function, and I don't think there is any way for
that to be safe.
