So the destructor_count will be in line with the remaining tests.  If the c3 container still has objects then the destructor_count will be off.

Is there a good way to do that on unsorted containers?

The cloned container is a snapshot of the objects at the time of the cloning.  When done, just destroy the cloned container.
