Indeed, that can certainly be an issue. I make sure to create new folders
specifically for training (though I end up not keeping the messages
because they're just too cumbersome), and whenever I run on an existing
folder, I ensure that it is expunged/compacted beforehand. It's
definitely a good warning, though, especially when trying to train on
folders with false hits moved out.
