Hi,

These might've been ask and answered already - can 't find it though. 

1. Why doesn't intrusive_ptr have reset( T* )? 

2. Why there is no something like this  provided by the header:

template<typename Derived>
class intrusive_base {
protected:
    intrusive_base() : m_counter( 0 ) {} 

private:
    friend void intrusive_ptr_add_ref( Derived* p ) { ++p->m_counter; }
    friend void intrusive_ptr_release( Derived* p ) { --p->m_counter; if(
!p->m_counter ) delete p;  } 

    unsigned m_counter;
};

to be used like this:
 
class Foo : intrusive_base<Foo> 
{
 ...
};

This should streamline intrusive_ptr class usage, isn't it? Or there is an
alternative way already?
