Yes it does. The GC might collect sooner wrt your example once in a blue
moon. This is all about determinism -vs- non-determinism.

No, as I pointed out elsewhere. (Tracing) GC behaviour is more complex
and harder to predict but not necessarily non-deterministic.

When I say non-deterministic wrt GC I mean that one cannot always show
_exactly_ when and where objects will be collected and destroyed.

Then we really mean "predictable" rather than "deterministic". GCs are
unpredictable whereas reference counting is not. Both can be deterministic.

Fair enough.
