Indeed, it would be interesting to generalize such a generic mechanism 
directly in Babel, and not in each OB plugins.

However, I am not sure neither how generic such a solution could be, and 
what would still be required to implement in each OB plugin. My (very 
little) experience so far is the Python prototype that John wrote, and 
then my analysis of the Clojure OB plugin. As I was explaining in this 
blog post, things are quite different between the two. In Python, it 
appears that one has to run a sub-process, in Clojure this is not 
necessary since we benefit the nREPL that handle that.

So far, the best idea about how to present async process I think is what 
John was proposing with the new window. Otherwise I still wonder about 
having a real background process for this thing to run such that one can 
continue to write things in the Org buffer while a code block is running 
in background. But as I explained, I will have to seriously look into 
Elisp in order to assess the full scope of such a task.

So far this is the only thing I have to say about that. In mean time I 
will fix my other patch, and then I will submit another one for this 
async feature (which will probably require much more review from your part).


Thanks,
