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

+a further limit of eight on the maximum depth of recursion, but that was
raised to 40 when a separate stack was implemented, so there is now
just the one limit.
