[ESS] Interactive SAS mode hangs

[Erin Jonaitis]

Sorry to be the bearer of bad news! But selfishly I am glad there is finally a rabbit at the bottom of this hole.

I've subscribed to the page on Github and will be excited for news of a fix, when someone in the community is able to contribute one. (Lisp is well outside my toolbox, so that someone will not be me, alas.) I know (or suspect anyway) that developing FOS software is often something done in one's spare time, and I appreciate the time you've already sunk into this problem.

In the meantime, we will use a workaround. If the workaround stops sufficing before there is a fix, would you expect 14.09 to be stable on RedHat 7 and Emacs 24.3.1? I don't have a clear sense of either release dates or how these pieces interact.

Unfortunately, I can reproduce that with M-x SAS: only one line at a
time works.  But that is definitely a bug since with 
M-x ess-sas-interactive I can submit regions, paragraphs, etc.  So I
made a bug report https://github.com/emacs-ess/ESS/issues/249
