Original issue's description:
> Relanding: Fixing crash that can occur if signal is modified while firing.
>
> The crash occurs if a slot causes the very next slot in iteration order
> to be disconnected.
>
> Relanding after fixing a race condition that this CL revealed. Previously
> the race resulted in an invalidated iterator, but now it will result in the
> iterator being modified, so TSan catches it.
