> Doesn't the destructor remove them from the containers?
No it doesn't. Since the object has not "backward pointer to the
container ('s !).
This means to be "right" ROOT (and any other C++ program too) must
scan ALL containers created to find out whether the deleted object
did belong one of them. But the last means one has to create the list
of all containers as well etc etc etc. It is some of the "well-known"
problem of C++.
