I realized now that the right way to implement the desktop auto-saving
is to activate an idle timer only on changes in the window configuration
The desktop file is mostly about remembering a list of buffers and
windows. There is no point in auto-saving each time point moves.
This is what web browsers do by auto-saving a list of tabs
only when you open/close a tab.
