well, ls and chmod are different utilities, so the -R could easily have
different effects despite having apparently the same function. 

I seem to recall once I did a chown -R something and it followed the
/. and /.. links in the directory so that it started walking up the
directory tree. luckily I stopped it. Perhaps chmod -R is doing a
similar thing?
