Ted Lemon sez:
 * Sure, make all the directories above them world executable but not
 * world readable.

Does not prevent chdir()ing up from the target directory.

 * Directories in which executables live have to be
 * readable or shells that keep command hash tables won't work, though.

Not true.  The hash tables will fail, but I believe notes are kept
internally to mark non-hashable directories as such, or at the very
least, an exec[lv]p is called which will, via brute force, tromp
through the entire path before giving up.

 * And I don't know what else might break - you'd have to try it and
 * see.
