--- Comment #2 from Marc Glisse <glisse at gcc dot gnu.org> --- I looked at this paper for a different project a while ago, and it doesn't seem like such a good match for C++ in general. While the basic idea looks simple (use 2 counters, one for the thread that created the object, one for the others), making it work in all cases is actually a lot of work. In particular the paper requires a runtime that periodically checks a queue in each thread.
