If it is to be the same as all other QObjects, then it should maintain
its current behavior I think. The destruction of children happens in
the QObject destructor. I don't even think one have to look at the
QObject destructor docs to understand that - where else would it be
done, considering the parent/child mechanism is a mechanism common to
all QObject-derived classes
