chmod cannot be used to stop people from going back down the directory
structure.  If you chmod -r they can still go back down, they just can't
*see* what's back there; but if, for example, you are worried about your
/etc/passwd file, the user can still access it.  If you use chmod -x the
user can't go back down, but then I should say they can't access *anything*
under a directory which has no execute permission.  So if you chmod -x /home,
not only can the user not go back into /home, but the user cannot even go
into /home/theuser.
