It's easy to argue about this, but numbers are more convincing. I don't know 
anything about instrumenting functions in Emacs; how can I find out how long 
Emacs spends running desktop-save over a particular time period?

So don't use long intervals: if the computer is idle anyway, why does it 
matter if Emacs does some work? Or does "idle" only apply to Emacs?
