It's not safe to delete QFactoryLoader
It's not safe to delete QFactoryLoader

If we delete QFactoryLoader and there's a QSensor[Backend] still being
held, we will explode. So either we do a refcount-type check and fatal
or we just don't delete QFactoryLoader. Since the process is about to
end anyway, don't delete QFactoryLoader.
