- * Solaris uses SPARC Total Store Order model.  In this model:

- *
- * In X86_64 atomic instructions set a full barrier and usual instructions

- *
- * An acquire barrier requires at least #LoadLoad and #LoadStore barriers

- *
- * A release barrier requires at least #LoadStore and #StoreStore barriers,
