Interesting... checked out back to that commit
(eff59a15d76647ce8282626b9eb463dc3706d56e) and it still doesn't work.
On a whim, I checked my pacman log (Arch's install system) and
coincidentally on Mar 20 /after/ I wrote that post in which things
work, I ran a system package update.

$ grep -i emacs /var/log/pacman.log

[2013-03-20 12:51] upgraded emacs (24.2-4 -> 24.3-1)

Using the Arch Rollback Machine, I downloaded Emacs 24.2.4 and
downgraded (also required downgrading imageMagick from 6.8.3.10 ->
6.8.2.3). Now it works again (refer to the reproducible example from
the mailing list post):
- http://www.mail-archive.com/emacs-orgmode@gnu.org/msg68238.html

Eric, your example fails for me. I get:

>>> x = 1
>>> return x
  File "<stdin>", line 1
SyntaxError: 'return' outside function

This works, hoever:

#+begin_src python :session
      x = 1
      x
#+end_src

#+RESULTS:
: 1

#+begin_src python :session
      x
#+end_src

#+RESULTS:
: 1

So, with emacs 24.2.4 and current Org-mode (pulled just now) and clean
make, *both* named and un-named sessions work for me on Arch Linux.
