It's possible to periodically update the desktop file buffer,
but not to save it, thus allowing normal auto-save to create
a #desktop# backup.  But this might cause some problems, e.g.
modes that call `save-some-buffers' like `compilation-mode'
will ask whether to save the updated desktop file.  Also it's
not clear how to restore the auto-saved backup copy after a crash.

OTOH, saving the desktop file buffer will create a desktop~ backup
that the user can restore when something goes wrong.  This is
implemented in the latest patch that is intended for the trunk.

Meanwhile, I installed the patch that temporarily disables the
autosave in `desktop-read' into the emacs-24 branch, so people
won't lose the desktop in case of errors.
