bug#9352: GNU/Emacs 23.3, Windows 7: Very huge .emacs-places can cause problems

["Christoph Conrad" <christoph.conrad@gmx.de>]

Hi,

after several investigation i found out the reason for crashing my emacs
crashing several times today.

I use

;; Shortcut for saving desktop and saveplaces
(global-set-key (kbd "S-<f9>")
                '( lambda ()
                   (interactive)
                   (save-place-alist-to-file)
                   (desktop-save desktop-dirname)))

sometimes t save my "session". Today emacs showed me a message after
that every time, "memory exhausted", and after two or three times he
crashed repeatable.

After some time i found out that my ".emacs-places" over the years had
reached a size of nearly 50 MB. I deleted it, problem gone.
