<p>
Note that if there are no read-write or write-write data races on memory location <i>x</i>,
then any read <i>r</i> on <i>x</i> has only one possible <i>W</i>(<i>r</i>):
the single <i>w</i> that immediately precedes it in the happens before order.

More generally, it can be shown that any Go program that is data-race-free,
meaning it has no program executions with read-write or write-write data races,
