 kernel spend too much time on just one path is one of them.  With
 symbolic links you can effectively generate much longer paths so some
 sort of limit is needed for the same reason.  Linux imposes a limit of

 raised to 40 when a separate stack was implemented, so there is now
 just the one limit.
