Hello,
I stumbled upon an interesting problem today. M-x emacs-version RET is
GNU Emacs 24.0.92.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.20.1) of
2011-12-22
I eval
(defvar a nil)
(setq a (selected-window))
in the *scratch*-Buffer. Then I work a little bit (2 minutes or so)
without touching the window that displays the *scratch* buffer. Then I
eval (window-live-p a) via M-: . In some cases (I cannot figure out
what to do exactly), nil is returned, although I did not touch the
window.
Whats wrong?
Adam

Hard to tell. Evaluate the below in *scratch* and we'll see whether
you really "did not touch the window" ;-)
Good luck, martin
(defvar my-suspicious-window nil)
(setq my-suspicious-window (selected-window))
(defun is-my-suspicious-window-still-live ()
(unless (window-live-p my-suspicious-window)
(message "My suspicious window was killed by `%s'" this-command)
(ding)
(setq my-suspicious-window (selected-window))))
(add-hook 'post-command-hook 'is-my-suspicious-window-still-live)
