There is another counter to direct counter using (I just think out loud -
it may be that you ok): what if I do not save all of the shared_ptr to the
same object? What will happened once they will get restored? Wouldn't it
cause memory leak?

I do realize that any other solution would be more complicated, but I think
we should go for it.
