It's not the destructor that kills the process in my case. One reason being that openUrl and startDetached are static methods. 

And, in the debugger, after the method is done, it steps back over all the stack variables, calling the destructors, and I can step all the way of the program and only at the very end does the started process die (longer after anything in the method has gone out of scope).
