Somewhat related, I had this left over from when I was working out the async code. It prevents the user from running :async without the (required) :session header. The :async header runs the default (blocking) process when :session is missing. diff --git a/lisp/ob-comint.el b/lisp/ob-comint.el index 86c2bf7a7..384bfcda8 100644 --- a/lisp/ob-comint.el +++ b/lisp/ob-comint.el @@ -206,11 +206,12 @@ comint outputs due to buffering.")
