Are the documentation authors monitoring this mailing list?

How about

template< typename T, typename Counter = int >
shared_ptr
{
   typedef Counter counter;  //counter type should be public

   template <typename DataAlloc = std::allocator<T>, typename CounterAlloc=std::allocator<counter>
>
   shared_ptr( const DataAlloc& da = DataAlloc(), const IntAlloc ia& = CountAlloc() );
};

I believe that the library authors should care about 
memory management most.
If they don't understand something, they should ask people around,
but I am convinced that the boost authors are the best (honest). 
I am sure that they can find a practical solution if they 
only wanted to.

Actually this is probably what the whole thread is about
to get people to try to find the best practicle solution
for memory management in the modern C++ age.
I am not sure that STL style allocators is the best
possible solution.
