[boost] [future] Will you provide allocators?

Hi,

Both implementation of futures used at least two call to new, one for T and 
one for the common class between the future and the promise.
Le me kno if I have missed something, do we really need the shared_ptr<T>? 
can't we use the future_object/future_impl class to store directly T.

On the Anthony implementation we see already the intent to use allocators 
for the promise construction

    // template <class Allocator> explicit promise(Allocator a);

but not for the new T in
    template<typename T>
    struct future_traits
    {
    typedef boost::scoped_ptr<T> storage_type;
    // ...
    static void init(storage_type& storage,source_reference_type 
t){storage.reset(new T(t));}
    //...
    }

Anthony, do you plan to use the same allocator for T?

Braddock, do you plan to use allocators?

Best
