Hmm. If I run IPython instead of regular python by setting this:
(setq org-babel-python-command "ipython --pylab --pdb --nosep")

Then org does not hang. It returns as expected. However, the 
capturing of output doesn't seem to work right.

In Org, the following:

#+begin_src python :session foo
x = 42
print x
#+end_src

Produces no RESULTS, and in the Python *foo* buffer I see:

In [8]: x = 42
In [9]: print x
42
In [10]: open('/var/folders/60/jb7kfrsn2jd90hpcgj4m_wrc0000gn/T/babel-35562TZV/python-3$
In [11]: 'org_babel_python_eoe'
Out[11]: 'org_babel_python_eoe'


But if I remove the "print" statment in Org:

#+begin_src python :session foo
x = 42
x
#+end_src

Then the RESULTS shows me 42, and the Python *foo* buffer is:

In [12]: x = 42
In [13]: x
Out[13]: 42
In [14]: open('/var/folders/60/jb7kfrsn2jd90hpcgj4m_wrc0000gn/T/babel-35562TZV/python-3$
In [15]: 'org_babel_python_eoe'
In [15]: Out[15]: 'org_babel_python_eoe'
