desktop.el: autosave?

[Reuben Thomas <rrt@sc3d.org>]

desktop.el is great; I've used it since before it became part of Emacs.

However, I sometimes lose my Emacs session for various reasons (hardly ever 
because of Emacs itself, usually for some stupid reason like updating a 
kernel, and then suspending instead of rebooting). When I come back, I get 
my old Emacs session. Of course, the files I'm editing all have auto-saved 
copies, if I need them. It would be nice if desktop mode could similarly 
write a desktop save file from time to time during the editing session so 
that if like me, you leave Emacs running all the time, you don't risk going 
back to a collection of files days or weeks out of date should you lose your 
Emacs session.

Since desktop already does things when Emacs is idle, it seems to me (I admit I 
know nothing about this area of programming Emacs, I've only dabbled in elisp 
to the extent I need to to customize Emacs) that it should be fairly simple to 
add the ability to save out a new desktop save file from time to time when 
Emacs is idle. I imagine the period would be customizable, but every half hour 
or so would seem to be the right order of default.
