Maybe, but I'm not sure: the amount of typing doesn't necessarily
present evidence of changes to the window configuration, visiting new
files or killing buffers, and other changes saved by desktop.el.  The
correlation between the two does exist, but it is much weaker than in
the case of auto-save of buffers.
