Why don't you just invert the order of clearing the bits:  

I think it should be an atomic operation. The original two-step clear itself is
problematic. So from this perspective, it is not just a solution to this
problem.

[resending, my MUA seems to have corrupted the CC list previously]

Can you show what breaks by it being non-atomic?

Because, again, the disable part is not atomic. Either it's needed on
both sides or it's not needed on either.
