> A cheaper, faster, less memory intensive, approach is eliminate the traversal by directly scanning the inode table.
> A side-effect is paths would be scanned and displayed in a random order. A new option, ex. "-direct" or "-fast", would likely be required to avoid compatibility issues.
> PS: This enhancement is valid only if the path is root directory {{/}}
