I've seen various historical issues with :session but it seems I may 
have a different problem. This is the latest org in emacs 24.3. If I 
do not have :session, then everything works just fine.

If I C-c C-c in the following code:

#+BEGIN_SRC python :session transect
import numpy as np
x = np.arange(12)
#+END_SRC

Emacs hangs the first time with minibuffer message of "Sent 
python-eldoc-setup-code". If I C-g, I can edit the org buffer again. 
All other invocations of that code and the minibuffer message is 
"executing Python code block...", but still emacs hangs until I C-g.

If I look at the *transect* buffer, I see the following. The code 
runs just fine, but for some reason it does not return.

   -k.
