[O] stty fails in babel sh blocks, workaround?

[George Jones]

I'm running some programs that expect to be able to get terminal
settings via (python fragment):

   ioctl(1, termios.TIOCGWINSZ, ' '*8))ioctl(1, termios.TIOCGWINSZ, ' '*8))

however, sh code run under babel appears not to have the terminal device
that's expected:

----------------------------nostty.org----------------------------
* No stty in babel

  #+BEGIN_SRC sh :results output :exports both
  exec 2>&1; date; set -e; # set -x; 
  stty || true
  #+END_SRC

  #+RESULTS:
  : Wed Apr  8 10:33:33 EDT 2015
  : stty: standard input: Inappropriate ioctl for device
------------------------------------------------------------------

I realize this is probably inherent to the design/the way babel works,
but are there any workaround (creating fake terminals, etc)?

Thanks,
