Hello all,
I just wanted to get some opinions on the following static allocation 
policy, revamped to ensure that there won't be alignment problems.  Does 
anything need to be revised?

    template < typename Type >
    class AllocateStatically
    {
    public:
        typedef Type * Pointer;

        static Pointer Create (  )
        {
            static Type instance;
            static bool first = true;

            if ( first )
            {
                first = false;
            }
            else
            {
                new ( reinterpret_cast < Pointer > ( &instance ) ) Type;
            }

            return &instance;
        }

        static void Destroy ( Pointer p )
        {
            p->~Type (  );
        }
    };
