Does piboxd take too much CPU?
On an 1.2 release of auto-kiosk, piboxd is taking 25% cpu on an RPi2. And that's without anything else running - no launcher, no apps. So something is really wrong there.
This may have been fixed with the use of semaphores but I need to check to be certain. I may have only added semaphore usage to the apps and not piboxd.
