True, but it is so clean and simple :)
Also, I thought DS would only be relevant for 16-bit code,
and moreover this will be (in the near future) the only
remnant of local handles we will have.

But yeah, we do have notifications to worry about, I guess
we have to push the set/restore closer to where it's needed.
