* order (first entry has offset == 0, last entry has the highest
* offset).
*
* When allocating new object we first check if there is room at
* the end total_size - (last_object_offset + last_object_size) >=
* alloc_size. If so we allocate new object there.
*
* When there is not enough room at the end, we start waiting for
* each sub object until we reach object_offset+object_size >=
* alloc_size, this object then become the sub object we return.
*
* Alignment can't be bigger than page size.
*
* Hole are not considered for allocation to keep things simple.
