My understanding is that checked_delete is intended to protect against freeing 
a pointer of an incomplete type, not against a missing virtual destructor. It 
is a tool of itself which can be used outside shared_ptr and in these cases a 
warning may be most appropriate. IMHO, if shared_ptr aims to support valid 
behavior in the lack of a virtual destructor, it should deal with the warnings 
itself.
