Well, the time has come and after many days of auto test battles we have an 
integration running in the CI system that targets QtDeclarative's dev branch 
and that - *fingers crossed* - should integrate. That's going to replace the v8 
dependency with a new built-in engine, that is still going to see a lot of 
further improvements (especially on the performance side) towards the release 
of Qt 5.2 (so nobody panic yet, please :)
