Does not look like the TODO will be resolved any time soon, so moving that into #182. The rest of this issue is done so marking as closed.

I think it's possible to use `O_NOFOLLOW` internally for `removePathRecursive`, but this cannot be done for `listDirectory` as that would change its behavior on symlinks. It would necessary to have...

Any such implementation would need to support Windows. I think it is possible, given that Cygwin implements it, but it involves touching some rather exotic APIs like [`NtQueryDirectoryFile`](https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/ntifs/nf-ntifs-ntquerydirectoryfile): https://github.com/Alexpux/Cygwin/blob/b39cd00f07e8df11c5446fb35da490ef85f12821/winsup/cygwin/fhandler_disk_file.cc#L2186 It's...

Would calling `lookupEnv "XDG_RUNTIME_DIR"` suffice? Is there any benefit from having this in `directory`?

Feel free to comment if there's still a concern. Thanks!
