Subject: bug#10114: 24.0.91; (not (eq (current-buffer) (window-buffer (selected-window))))

When you remove the current buffer from the selected window,
the buffer that gets displayed in the selected window isn't always
the same as the buffer that gets made the new current buffer.
The command M-x test (see below) manifests the problem
for me from runemacs -Q.

Output on Emacs 23.3:
Current: *Test*<2>; Selected: *Test*<2>; [...]
Current: *Test*<1>; Selected: *Test*<1>; [...]

Output on Emacs bzr trunk:
Current: *Test*<2>; Selected: *Test*<2>; [...]
Current: *Test*<1>; Selected: *scratch*; [...]

(defun test ()
  (interactive)
  (progn
    ;; This seems to sow enough confusion.
    (switch-to-buffer-other-window "*Test*<1>")
    (switch-to-buffer-other-window "*Test*<2>")
    (delete-other-windows))
  (while
      (progn
        (message
         "Current: %s; Selected: %s; \
type k to kill current buffer, \
any other key to quit"
         (current-buffer)
         (window-buffer (selected-window)))
        (and (eq (read-event) ?k)
	     (kill-buffer))))
