The way it is being handled is explained here:
https://svn.boost.org/svn/boost/sandbox/block_ptr/libs/smart_ptr/doc/rationale.html#cyclicism

If blocks of memory are found to still exist after a standard reference 
counter destruction and that the pointer is living on the stack or data 
segment then each memory blocks will be destructed and deallocated in 
the order they were constructed (FIFO).  Everything is being handled 
implicitly.
