[Development] Suggestion: how to know when object is scheduled for deletion

[Alan Ezust]

Looking at the implementation of deleteLater:
{
     QCoreApplication::postEvent(this, new QDeferredDeleteEvent());
}

It seems to me you can achieve what you want without modifying the
implementation of deleteLater(), and instead making an event filter on
QCoreApplication for QDeferredDeleteEvent.
