> There is still no guarantee the method return is equivalent/isochronous with the property change. Sure there is. We know udisks has completely finished mounting a filesystem, therefore we know udisks property about whether the file system is mounted will have changed. It's equivalent to calling QLabel::setText and then after it returns knowing you can get the right result from QLabel::text That's not relying on an implementation detail, it's that anything else would be a definite bug.
