> Synchronization actions induce the synchronized-with relation on actions, defined as follows:
> EA write to a volatile variable (˜8.3.1.4) v synchronizes-with all subsequent reads of v
> @by any thread (where subsequent is defined according to the synchronization order).
> If we have two actions x and y, we write hb(x, y) to indicate that x happens-before y.
> EIf x and y are actions of the same thread and x comes before y in program order, then hb(x, y).
> EIf an action x synchronizes-with a following action y, then we also have hb(x, y).
