Good idea, thank you. I have added an experimental boost/intrusive_ptr.hpp
to the CVS. A simple demonstration:

#include <boost/shared_ptr.hpp>
#include <boost/intrusive_ptr.hpp>

#include <iostream>

struct X: public boost::counted_base
{
 X(): boost::counted_base(0, 0)
 {
  std::cout << "X::X()\n";
 }

 ~X()
 {
  std::cout << "X::~X()\n";
 }
};

int main()
{
 boost::intrusive_ptr<X> px(new X);
 boost::intrusive_ptr<X> px2(px);
 boost::shared_ptr<X> px3(px2);

 px = 0;
 px2 = 0;
}
