  Ah, I think I follow.

So in C++ terms:
  It basically requires either a global shared_ptr, or that you 
passed one around by reference between threads. And that you then 
killed it in one thread at the exact moment the control block was 
read in another thread. That blog post discusses a solution, I 
wonder if that is implemented in C++'s shared_ptr?
