[mir-only] CPU 50% doing nothing and Apps in the background are running

[Pat McGowan]

Open a bunch of apps, like gallery, terminal, file manager.
Have file manager in the foreground
Open ssh conectiona nd run "top"
Rotate the phone and you can see all sorts of app activity as they rotate.
CPU never goes to 0 as it does on SF, tend to stay around .3%.

The apps are initially stopped correctly. Going back to them from the dash then back to the dash is also fine.
Cycling through apps using the right edge is what triggers them to no longer be suspended.

debs from trunk via http://people.canonical.com/~ricmm/pat-testing/ fix the problem
but unity is running at 50%+ cpu without doing anything

believed to be fixed with https://code.launchpad.net/~gerboland/unity-mir/add-fail-and-resume-focus-support/+merge/188040 fixes only the apps running in the background

investigation still required for the cpu 50% hogging
