However, AFAICS, it comes with a serious problem. Immutable

immutable RC object could easily be counting atomically for
nothing.
Argh! I didn't think about this. Any chance we can deprecate
this behaviour? It's also an obstacle for the implementation of
thread-local heaps.
No way! Neither for joke, please!
