It's weird that he excludes data races from the memory safety even though data races can be in the other classes he calls out. Not sure I buy that it's not as relevant for security since use-after-free is a common side effect of data races.

I am also a little confused by it, but we'll see how it goes. Since everything is still subject to change, it's possible that this won't be the final word on the matter, so I'm not too concerned at this stage.
