I do agree with Hans. I could of course add the flag to my code. It
might however be better to do it after the 3.8 release and do it both
on my classes and on the current demons classes (with different
default behaviors to keep backwards compatibility on the current class
and the "nicer" behavior on the new classes).

Great!
