The short answer to that is that this bug leaves shared memory in
a corrupt state. It's not really useful to worry about whether
readers should react differently to that --- you could spend endless
amounts of time hypothesizing different kinds of corruption and
endless amounts of code/cycles trying to work around it. But the
right answer is to fix it on the writing side.
