The :post method does not seem to work for me. With:

--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC sh :results output  :post (shell-command-to-string "popup.py babel done")
sleep 10
echo DONE
#+END_SRC
--8<---------------cut here---------------end--------------->8---

(popup.py is my homemade notifier) I get the popup immediately and the
results after 10 seconds.  The org-babel-after-execute-hook method
worked fine.
