The iplimits.txt file in the shared_cyclic_ptr files directory also illustrates
why raw pointers need to be followed.  Search for:

   2)"pointer cycle with raw cut" -

This also hints at what was lacking in Detlef's article: an explanation
of how to handle containers of smart pointers.  This is handled by the
shared_cyclic_container template defined in shared_cyclic_ptr.hpp.
