Forgot about that; a global reference count lock might work well, but this
could negatively impact performance in the case of things like argument
tuples.  Perhaps internal objects that are guaranteed to be thread-local
can skip the reference-count-locking step, but I'm not sure how many (if
any) objects can guarantee this.
