I've been considering the impact of the new built-in commands in
ksh-2014-09-29 on restricted mode. Many of the new built-ins circumvent
the restrictions imposed by restricted mode. So, I started rksh with
PATH=/rbin, and to my surprise none of the new "built-ins" were
accessible. So far, so good. But, when I repeated the experiment with
PATH unset all of the built-ins were again accessible in rksh. Something
to keep in mind when setting up a restricted ksh environment.
