I visited Insignia Solutions last year.  At that time, they told me
about "idle detection" algorithms that they were working on.  These
algorithms were supposed to detect code execution patterns that would
indicate that the MS-DOS program (or MS-DOS itself) was spinning
(waiting for input, for example).  Perhaps someone knows if they have
made any progress in this area...
