Well, this is how I interpreted the original request. ;-)

This is how I understood your change mentioned above: ESS will spawn a  
new S process as soon as we try to execute code in an S buffer that is  
not already associated with an ess process --- regardless if there is  
an ess process already running. If I'm correct, I'm not sure I like  
this feature.

Thanks for your work on this.
