Isn't this potentially racey as well? I can see that fchdir(old); will
definately take you back to the parent of "foo" but how can you be sure
that the directories aren't moved around between step 1 and 2? You
could end up in a different "foo" to what you intended, I guess this is
a different issue - but it is still an issue isn't it?
