Stop/Start with a turbo engine - problems?

I am interested in buying the latest Ford Focus Titanium with the Turbo 150bhp engine has STOP technology. If as is suggested by Honest John Turbos must be idled after running at speed to allow them to cool down how does the STOP technology deal with this problem if at all?

If the turbo is too hot the engine doesn't stop.
