Yes. Replacing `split-window' by
(progn
(split-window)
(message "sel %s .. lru %s" (selected-window) (get-lru-window)))
shows the problem immediately. Everything seems alright when you put
that message into my-walk.
run_window_configuration_change_hook selects each window before running
the hook buffer-locally which makes any reasoning (within the function
run by the hook) about which window will be selected when the command
completes void. In addition it unwinds with select_window_norecord
which won't restore the current buffer when the selected window gets
reselected. Both of these don't explain the problem that somewhere
`select-window' must get called with norecord nil :-(
