/* sub-allocation manager, it has to be protected by another lock.

 * Principe is simple, we keep a list of sub allocation in offset
 * 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.
 * Assumption is that there won't be hole (all object on same
 * alignment).
