How does make_space_for_item assure the return value is aligned properly for an Item type? [snip]
Well, I guess it would also need some kind of handler->alignment(). make_space_for_item(handler->size(), handler->alignment()); you would look at the end of the vector<char> and see if it aligns or how much you need to fudge there. So add enough for alignment + size and return the aligned address.
