Ok, testing with a parented QDialog() was an erroneous test, you are right.
But I keep seeing a memory leak with 'f = QDialog()', with a slower rate
that the parented one has. Note that I'm having also memory leaks with
"f = QString('1234 1234')" and  "f = QCustomEvent(1)". 

I'm attaching the logs for these, please check if you can't see the
"f = QDialog()" memory leak after the same number of iterations that I do
(I added the iteration number to the log). The same for QString and

I will install Gentoo to check this on that distribution.
