I'm curious how you get that 16 GB number. It was my understanding
that if T is a small movable type, then a QList<T> is just an array of
T.  So 2 billion elements would only mean sizeof(T) * 2 billion, just
like a QVector. With sizeof(T) == 4, that's only 8 GB. Are you
assuming sizeof(T) == 8, or is there something else ?
