+//
+// According to the new Java Memory Model (JMM):

+// (2) A read cannot let unrelated NON-volatile memory refs that
+//     happen after the read float up to before the read.  It's OK for
+//     non-volatile memory refs that happen before the volatile read to
+//     float down below it.
+// (3) Similar a volatile write cannot let unrelated NON-volatile
+//     memory refs that happen BEFORE the write float down to after the
+//     write.  It's OK for non-volatile memory refs that happen after the
+//     volatile write to float up before it.
+//
+// We only put in barriers around volatile refs (they are expensive),

-// memory barrier (i.e., it's not sufficient that the interpreter does not
-// reorder volatile references, the hardware also must not reorder them).
-//
-// According to the new Java Memory Model (JMM):
-// (1) All volatiles are serialized wrt to each other.
-// ALSO reads & writes act as aquire & release, so:
-// (2) A read cannot let unrelated NON-volatile memory refs that happen after
-// the read float up to before the read.  It's OK for non-volatile memory refs
-// that happen before the volatile read to float down below it.
-// (3) Similar a volatile write cannot let unrelated NON-volatile memory refs
-// that happen BEFORE the write float down to after the write.  It's OK for
-// non-volatile memory refs that happen after the volatile write to float up
-// before it.
-//
-// We only put in barriers around volatile refs (they are expensive), not
-// _between_ memory refs (that would require us to track the flavor of the
-// previous memory refs).  Requirements (2) and (3) require some barriers
-// before volatile stores and after volatile loads.  These nearly cover
