I'll start by adding a "forced" destruction member.  It will decrement the 
pointer, followed by a self-destruct placed_ptr call.  This way at least 
the programmer will be able to free his own cyclic container.

... or maybe operator delete could be displaced for placed_ptr<> or other 
rc pointer types.  What do you think?

Other areas seems to be copyrighted and chances are we'll have to adapt it 
so it depends on their opinion mostly I guess.
