[BUG] ob-python: async session evaluation does not support python-mode.el [9.6-pre (release_9.5.5-2661-g2d040b.dirty @ /home/yantar92/.emacs.d/straight/build/org/)]

[Ihor Radchenko]

Hi,

Commit 53fd5b774 introduced async session support in Python src blocks:

ob-comint.el, ob-python.el: Async session evaluation

Adds functionality to ob-comint.el to implement async session eval on
a per-language basis.  Adds a reference implementation for ob-python.

However, async evaluation fails when org-babel-python-mode is set to
'python-mode.

MWE:

Executing

#+begin_src python :session :async yes :results output
import time
time.sleep(.1)
print('Yep!')
#+end_src

will never yield.

This is because org-babel-python-async-evaluate-session assumes that
built-in python.el is used to initiate the python session, which is not
the case when org-babel-python-mode is set to 'python-mode.

See org-babel-python-initiate-session-by-key.
