/*
 The following data comes from a user for whom this code
 indicated that Dropbox was always busy, when the two thresholds were
 set to 1.0 and 0.25 percent.  This is why I just increased them both to 2.0
 percent.  That probably makes this class not very useful, because there will
 be missed detections for the average user.  That is, on my Mac, settings of
 1.0 and 0.25 percent work perfectly well because my Dropbox CPU
 falls to 0.0 when it's not uploading or downloading anything.
