Removing the dependency to the parent pointer solves many issues with non-atomic updates of children's parent pointers with respect to any move operations. However, this comes with an embarrassingly terrible runtime as the only other option is to exhaustively check every dir entry to find a child's parent. Fortunately, deorphaning should be a relatively rare operation.
