Dan, what if you later want to do some cleanup at seton-lr time, no
matter where LR is seton?  I think having an exit subr is a good idea,
although I think it should also do a return to be worthy of the name
exit.  Then it would have two lines! :) (Naming it "exit" and not having
it return makes me suspicious that the programmer thought that just
setting on LR would make the program end immediately.)
