aussie reply:
 I think DD learned of the Dark Wizard's Horcrux much earlier than
1945 when he finally defeated him. That is why, according to
Slughorn's memory, DD was so aggresively against the teaching of
Horcruxes while Tom was still at school. It had to do with something
that PRE-dated Tom's showing himself to be someone DD had to be
cautious of.
