> What happened to this patch to add sort-of-file-locking to desktop.el?

As far as I know, nothing has been done with it.  I still have it in my
working copy (of course), and have, prompted by your message, just now
resolved a daunting 57/76-line conflict with the changes between 1.106 and
1.108.  My version has one of the tainted `mapc' calls, if that matters;
given Stefan's trivial (dolist (x l) (f x)) I would surely have supplied
(mapc f l) myself.  (No offense meant to Stefan; that one alone was
trivial.)

I've attached an updated patch vs. current CVS; in it I have
optimistically tagged my two new defcustoms as new in 22.2.  Here's a stab
at a ChangeLog:

2007-06-08  Davis Herring  <herring@lanl.gov>

	* desktop.el (desktop-save-mode-off): New function.
	(desktop-base-lock-name, desktop-not-loaded-hook): New variables.
	(desktop-full-lock-name, desktop-file-modtime, desktop-owner)
	(desktop-claim-lock, desktop-release-lock): New functions.
	(desktop-kill): Tell `desktop-save' that this is the last save.
	Release the lock afterwards.
	(desktop-buffer-info): New function.
	(desktop-save): Use it.  Run `desktop-save-hook' where the doc
	says to.  Detect conflicts, and manage the lock.
	(desktop-read): Detect conflicts.  Manage the lock.
