In a threaded environment, it shouldn't really be
a problem as long as the view of the data is consistent.
It's no different from what would have happened if the
reading thread had got there just a moment sooner,
before the writer got hold of it.
If that's a problem, there should have been some
higher-level synchronisation going on before getting
to that point.
