An RSS feed I follow mentioned ob-async here:
https://github.com/astahlman/ob-async
I haven't seen it mentioned on the list yet. Perhaps others would be
interested in asynchronous Babel processing. I've seen the feature
requested often on this list.
-k.

This is not the first attempt to my knowledge. I know of:
- my hacky attempt https://github.com/stsquad/async-org-babel
- John Kitchen's python specific version http://kitchingroup.cheme.cmu.edu/blog/2015/11/20/Asynchronously-running-python-blocks-in-org-mode/
- this matlab version http://emacs.stackexchange.com/questions/21301/async-execution-in-org-babel
So I think there have been enough proof of concepts of using async.el
and inserting results at a later date. I think what would be really
useful is some feedback from the org-mode maintainers about the various
approaches and if something generic could be included with org-mode
itself.
Any thoughts?

I never used any of these, so please take this with a grain of salt.
AFAIU, these solutions are too limited at the moment. They suffer from
the same problem as current ":cache" parameter, i.e., they seem unable
to cope with blocks that refer and execute other blocks.
IMO, for anything serious, we need to implement something that is able
to capture the "closure" of a block. In this case, all blocks belonging
to that closure would be marked as read-only during the process, so as
to avoid race conditions. We also need to be able to retrieve all the
results from all the blocks involved.

Hello,
I installed ob-async from MELPA. It does not seem to work. For example
the following simple source block is run synchronously, i.e., emacs
shows the cursor as a watch and it is not possible to move point, or to
type, until the source block completes.
#+begin_src ruby :tangle test.rb
sleep 30
puts "Hello World"
#+end_src
#+begin_src sh :results output :async
ruby test.rb
#+end_src
#+RESULTS:
: Hello World
Is ob-async known to be broken? I'm using
GNU Emacs 27.2 (build 1, amd64-portbld-freebsd12.2, X toolkit, cairo version 1.17.4, Xaw3d scroll bars)
Org mode version 9.5.4 (release_9.5.4-602-g381a2a.dirty @ /home/rmason/.emacs.d/org-git/lisp/)
Thanks for any help.
Roger

No. The user is broken.
It seems ob-async must be required in the file in which it is to be used
(I had it in my init file). I ran into a further problem that is
resolved using:
(defun no-hide-overlays (orig-fun &rest args)
(setq org-babel-hide-result-overlays nil))
(advice-add 'ob-async-org-babel-execute-src-block :before
#'no-hide-overlays)
See:
https://www.reddit.com/r/emacs/comments/v2p4q9/orgbabel_problems_with_obasync/
Sorry for the noise.
Roger
