unity-scope-loader is adding the SAME inotify watches regularly every 4 seconds

[Colin Ian King]

unity-scope-loader is adding the SAME inotify watches regularly every 4 seconds:

Inotify watches added:
  PID Process Rate/Sec File
  3495 unity-scope-loader 0.250 /usr/share/upstart/xdg/menus/unity-lens-applications-merged
  3495 unity-scope-loader 0.250 /etc/xdg/menus/unity-lens-applications-merged
  3495 unity-scope-loader 0.250 /usr/share/upstart/xdg/menus
  3495 unity-scope-loader 0.250 /usr/local/share/applications
  3495 unity-scope-loader 0.250 /usr/share/ubuntu/applications
  3495 unity-scope-loader 0.250 /home/king/.config/menus/unity-lens-applications-merged
  3495 unity-scope-loader 0.250 /etc/xdg/xdg-ubuntu/menus
  3495 unity-scope-loader 0.250 /etc/xdg/xdg-ubuntu/menus/unity-lens-applications-merged

I'm seeing every 4 seconds the *same* files being added to an inotify watch. Additionally, the code is polling every 4 seconds to do this:

Top polling system calls:
  PID Process Syscall Rate/Sec Infinite Zero Minimum Maximum Average
                                                           Timeouts Timeouts Timeout Timeout Timeout
  3476 unity-scope-loader poll 0.0167 2 3 0.0 sec 0.0 sec 0.0 sec
  3495 unity-scope-loader poll 0.2500 0 0 4.0 sec 4.0 sec 4.0 sec
 Total 0.2667 2 3

the timeout is set to just 4 seconds. Is this heavy polling and repeated inotify watch adding really required? We're trying to get the battery life to last longer and this kind of polling activity just is rather anti-social if it is not necessary.

Attached are the results of a 5 minute analysis from the health-check too.
