"Web[2010]. In TSO, each sequential thread carries its own write buffer that serves as the initial target of the writes executed by the thread. Thus, TSO permits executions that are not possible with SC. To illustrate this relaxed behavior let us consider the canonical example depicted in 1 below. We have two sequential threads running in parallel. " - Tso relaxed
