Before Boost I had my own version of shared pointer that used an
intrusive method. This was the most interesting part of using the
intrusive method.

The intrusive method allows you to move from shared_ptr to raw pointer
and back to shared pointer. This is not a common application of
shared_ptr which is why the non-intrusive version is so popular. But when
you need intrusive, you know you need it.
