The one that I was last in before going to the active process (or something more intelligent such as what is suggested by C-x b [that typically knows very well which buffer I want to change to]).

I was imprecise here, sorry for that. 

I have two buffers displayed vertically. The top buffer showing foo.R, the bottom buffer the active R process. I then change to the R process via C-x o and kill it via C-x k. Then I still see foo.R on top, but the buffer shown at the bottom is one of the buffers I previously loaded since the last start of Emacs. In almost all cases you have to type C-x 0 again to change back to the top buffer (showing foo.R) and close the (useless) buffer at the bottom.

Cheers,

Marius
