2617// without some kind of memory barrier (i.e., it's not sufficient that
2618// the interpreter does not reorder volatile references, the hardware
2619// also must not reorder them).
2620//
2621// According to the new Java Memory Model (JMM):
2622// (1) All volatiles are serialized wrt to each other. ALSO reads &
2623// writes act as aquire & release, so:
2624// (2) A read cannot let unrelated NON-volatile memory refs that
2625// happen after the read float up to before the read. It's OK for
2626// non-volatile memory refs that happen before the volatile read to
2627// float down below it.
2628// (3) Similar a volatile write cannot let unrelated NON-volatile
2629// memory refs that happen BEFORE the write float down to after the
2630// write. It's OK for non-volatile memory refs that happen after the
2631// volatile write to float up before it.
2632//
2633// We only put in barriers around volatile refs (they are expensive),
