                      Using the aligned allocator with a minimum Alignment value
                      is generally only useful with containers that are not node-based

                      the node object would have the minimum alignment instead of
                      the value type object.

          Except for the destructor, member functions of the aligned allocator shall
          not introduce data races as a result of concurrent calls to those member
          functions from different threads. Calls to these functions that allocate
          or deallocate a particular unit of storage shall occur in a single total
          order, and each such deallocation call shall happen before the next allocation
          (if any) in this order.
