I still don't like that we're copying code between KD and KD64 instead of sharing it.
But as both modules are totally distinct at the moment, I won't be the one introducing shared functions between them.
This is a follow up to 50ae5e7c52
, which TortoiseGit accidentally turned into a "Message only" commit...
Never hit ALT+Y by mistake! ;)
