how to get focus-follows-mouse over buffers in ema

问题:

Suppose I have a source file open and I launch a shell. I can hit C-x o to switch between the two buffers. But how can I get it so that when I move the mouse the buffer under the mouse gets focus, just like the "focus follows mouse" option common in window managers?
