+Subject: PATCH top: lessen summary cpu distortions with first display
+
+When the cpu utilization is displayed for
+the first time, the reading of the /proc/stat
+file is very close to each other, resulting
+in large fluctuations. The version before
+refactoring, such as v3.3.17, has a delay
+before reading the /proc/stat file for the
+second time, and the same delay is added here.
