Sounds like a good idea to me.

Problem to solve: KApplication derives from KInstance. So if KApplication is 
destructed before the global statics how could KInstance keep itself alive 
long enough? I guess KInstance then has to be a member of KApplication. What 
implications does that have on existing code?
