Iromlab doesn't exit if Finalize button is pressed after last disc has been processed

Possibly related/same issue: while running iromlab from console this happened after pressing Finalize:

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Python36\lib\tkinter\__init__.py", line 1699, in __call__
    return self.func(*args)

    return self._configure('configure', cnf, kw)
  File "C:\Python36\lib\tkinter\__init__.py", line 1470, in _configure
    self.tk.call(_flatten((self._w, cmd)) + self._options(cnf))
KeyboardInterrupt

This happens after the operator pressed the confirmation button and after the removal of jobs / jobsFailed folders. Error is related to logging --> perhaps KeyboardInterrupt interferes with displaying/writing to the log? In that case pausing a few seconds before thread.interrupt_main() might do the trick.
