This should be the last step to removing the need for parent entries. Parent entries cause all sort of problems with atomic directory updates, especially related to moving/deleting directories. I couldn't figure out a parser for '..' entries without, O(n^2) runtime, a stack, or modifying the path itself. Since the goal is constant memory consumption, I went with the O(n^2) runtime solution, but this may need to be optimized later.
