Are you sure this need special handling?
I think the purpose of enable_shared_from_this is to make weak reference to 
self and maintain it automatically. You don't do anything special when 
constructing a shared_ptr with enable_shared_from_this-derived or when 
calling make_shared with it. And before 1.41 everything worked just fine!
