I see. But `kill-buffer' calls `replace-buffer-in-windows' which
doesn't call `other-buffer'. Only if the buffer to be killed is still
current after that, `kill-buffer' calls `other-buffer'. In the scenario
above it is not called.
Why is showing the buffer visiting /tmp/xx bad in your scenario? Can
you give a scenario where the present behavior really hurts you? In
that case we can try to ignore such a buffer in `switch-to-prev-buffer'.
