I do not think so, getters return a copy of the thread's address.

I am not familiar with herd7 tool and with ARM nuances, but I do not think the example is relevant. This scenario cannot be applied to **this particular case**, as we never will have update of the value happening concurrently with the read, as there is a expensive operation between the two. Let's not overengineer the solution for this failing code path.
