org 8.2.3 ?? The last 8.2.3 release I see on git is 2013-11-15 05:58:32 
(GMT)

The ess 14 patch showed up on 2014-09-18 01:10:40 (GMT).

Yes. (R) starts the session asynchronously, so in programmatic use
subsequent commands can jump the queue and confuse the process. 

This did not seem to matter before ess 14.

The 2014-09-18 01:10:40 (GMT) patch forces a wait for (R) to finish before
anymore commands are sent to the session.

So either update org-mode or downdate ess or replace
org-babel-R-initiate-session with the current version and recompile.

HTH,
