If the shared_ptr is passed around by value, as a regular (*) pointer 
would be, it will correctly keep track of the reference count and delete 
only when there are no more referrers. -- That's basically the whole 
point of shared_ptr. If you didn't want the reference count you could 
just use scoped_ptr or std::auto_ptr.
