[boost] scoped_allocator_ptr

Hi, Is there an interest in a scoped_ptr that receives a Allocator parameter? I've been needing this in some libraries I've been developing. It could use EBO for the Allocator parameter to have the same size as scoped_ptr for empty Allocators. I need a move_ptr with a Allocator parameter too. But I rather let somebody else write for now. Thanks, -- Felipe Magno de Almeida
