Woops, sorry it was a typo. I meant page 411, not 413. It says it's an
error there. Btw, I never said ++ was atomic, I've asked whether
something has changed. IOW I thought perhaps this used to be an error
but maybe it was changed to make increment/decrement to be atomic on
shared variables. That's not the case of course..
