519 * When allocating new object we first check if there is room at
520 * the end total_size - (last_object_offset + last_object_size) >=
521 * alloc_size. If so we allocate new object there.
522 *
523 * When there is not enough room at the end, we start waiting for
524 * each sub object until we reach object_offset+object_size >=
525 * alloc_size, this object then become the sub object we return.

527 * Alignment can't be bigger than page size.
528 *
529 * Hole are not considered for allocation to keep things simple.
530 * Assumption is that there won't be hole (all object on same
531 * alignment).
