I'm going to need someone else to make the decision:
 A) leave it here
 B) Move it to PerformanceMetrics
 C) Create a new Metrics module that Loic will later extend

Who can make a call on this?

I think the "That is the program has loaded enough buttons, labels, etc. so that the user can now start using it." should be enough for people to understand it, but if you have a better wording/suggestion i'm open to adding that instead.

Added as Recommends, liblttng-ust0 is required by lots of stuff on the phone, so yes it's already in the image.
