The part in kuniqueapplication.cpp is evident, but I haven't got a clue what 
you're trying to do in kapplication.cpp. You'll need to explain.

The rest looks ok.

Looking at the code today I see many uses of ::exit in both sides of the fork, 
which is bad. This should be cleaned up, but since it's been like that for 
ages, let's just leave it.
