[ESS] Is there a way to continue using emacs while C-c C-r ess-eval-region is running?

Thank you. I tried setting ess-eval-visibly-p to nil. But now all I see in the R process (ESS[S]) buffer is:

This is generally confusing, and makes it tempting to put print statements in the code. Surely this would be a step backwards.  

What I need is for the R process to be allowed to lag behind, and for my code to be interleaved with evaluation results as they occur.

So, FWIW, I think the ESS default setting is correct.
