* [BUG] ob-shell async session does not work with multiple blocks running [9.7.16 (9.7.16-ba9734 @ /nix/store/6la93ywyb1h055phgyqba7h7qay60p0m-emacs-packages-deps/share/emacs/site-lisp/elpa/org-9.7.16/)]

Problem: Running two shell source blocks with the same session doesn't
properly extract out results from the sentinel value relating to each
respective source block.
This could be a known issue which might make this an enhancement request
rather than a bug report.
Expected: Running two source blocks at once to properly deal with only
their values from the "foo-comint-indirect" buffer.
Given:
#+begin_src sh :session foo :async
sleep 5
echo "almost done"
sleep 3
echo "done"
#+end_src
#+begin_src sh :session foo :async
sleep 1
echo "almost done"
sleep 6
echo "done"
#+end_src
Then running these right after another using:
M-< ;; beginning-of-buffer
C-c C-v C-n ;; org-babel-next-src-block
C-c C-c ;; org-ctrl-c-ctrl-c
C-c C-v C-n ;; org-babel-next-src-block
C-c C-c ;; org-ctrl-c-ctrl-c
You never get the results for the last source block, but there are 3
stages:
1. After evaluating each block, but before either is done:
#+begin_src sh :session foo :async
sleep 5
echo "almost done"
sleep 3
echo "done"
#+end_src
#+RESULTS:
: 4466c6fe-e7b5-4c14-9cae-d8f066ec6ebf
#+begin_src sh :session foo :async
sleep 1
echo "almost done"
sleep 6
echo "done"
#+end_src
#+RESULTS:
: 17c8a088-82c4-4695-90f6-fe3cba9fcfd7
2. After the first is finished running (notice the clobbered results
pulled in from the other block, this is the bug)
#+begin_src sh :session foo :async
sleep 5
echo "almost done"
sleep 3
echo "done"
#+end_src
#+RESULTS:
: echo 'ob_comint_async_shell_start_17c8a088-82c4-4695-90f6-fe3cba9fcfd7'
: sleep 1
: echo "almost done"
: sleep 6
: echo "done"
: echo 'ob_comint_async_shell_end_17c8a088-82c4-4695-90f6-fe3cba9fcfd7'
: almost done
: done
#+begin_src sh :session foo :async
sleep 1
echo "almost done"
sleep 6
echo "done"
#+end_src
#+RESULTS:
: 17c8a088-82c4-4695-90f6-fe3cba9fcfd7
3. Something is done to fixup the results from the first source block,
but the second source block never gets updated with it's results
#+begin_src sh :session foo :async
sleep 5
echo "almost done"
sleep 3
echo "done"
#+end_src
#+RESULTS:
: almost done
: done
#+begin_src sh :session foo :async
sleep 1
echo "almost done"
sleep 6
echo "done"
#+end_src
#+RESULTS:
: 17c8a088-82c4-4695-90f6-fe3cba9fcfd7
Here is what the foo-comint-indirect buffer looks like:
org_babel_sh_prompt> echo 'ob_comint_async_shell_start_4466c6fe-e7b5-4c14-9cae-d8f066ec6ebf'
sleep 5
echo "almost done"
sleep 3
echo "done"
echo 'ob_comint_async_shell_end_4466c6fe-e7b5-4c14-9cae-d8f066ec6ebf'
ob_comint_async_shell_start_4466c6fe-e7b5-4c14-9cae-d8f066ec6ebf

echo 'ob_comint_async_shell_end_17c8a088-82c4-4695-90f6-fe3cba9fcfd7'

Thanks for the great feature. Just allowing for long running shell
blocks to not block doing things in emacs was a great addition.
