  * The strategy of this test is:
  * We install QSignalSpy instances on many signals from KGlobalSettings::self(),
  * and then we get another process (kglobalsettingsclient) to call emitChange(),
  * and we check that the corresponding signals are emitted, i.e. that our process
  * got the dbus signal.
  *
  * As a nice side-effect we automatically test a bit of KProcess as well :)
