+ * final or volatile qualifiers. These differ from unqualified
+ * versions in that (1) they check for read-only status (2) they use
+ * the volatile forms of Unsafe get/put methods. (When accessed via

+ * the volatile forms are heavier than necessary in terms of
+ * underlying reordering rules and memory barriers, but preserve
+ * correctness.)
