   It's a tricky area.  If you use an open file descriptor per
   directory, you can always get back to where you came from.  If not,
   then you can run into other problems.

perhaps restricting ftw usage to "depth" mode would help.  in that case,
only a parent chain of directory descriptors is needed, i would think,
and so a smart implementation could make do w/ O(filesytstem-depth) fds
(for directories).
