1. Open a project.
2. Check "Run in terminal" in run settings.
3. Run the project.
4. After the program finished, try to close Creator's Application Output tab.
   Creator will warn that the program is still running and ask for confirmation. This happens because qtcreator_process_stub is still running.

Now run the project in debugger instead. The warning will not be shown although qtcreator_process_stub is still running.

I think Creator should show the same behaviour in both situations.
