- * A handful of basic atomic operations.  The appropriate pthread
- * functions should be used instead of these whenever possible.
- *
- * The "acquire" and "release" terms can be defined intuitively in terms
- * of the placement of memory barriers in a simple lock implementation:
- *   - wait until compare-and-swap(lock-is-free --> lock-is-held) succeeds
- *   - barrier
- *   - [do work]
- *   - barrier
- *   - store(lock-is-free)
- * In very crude terms, the initial (acquire) barrier prevents any of the
- * "work" from happening before the lock is held, and the later (release)
- * barrier ensures that all of the work happens before the lock is released.
- * (Think of cached writes, cache read-ahead, and instruction reordering
- * around the CAS and store instructions.)
- *
- * The barriers must apply to both the compiler and the CPU.  Note it is
- * legal for instructions that occur before an "acquire" barrier to be
- * moved down below it, and for instructions that occur after a "release"
- * barrier to be moved up above it.
- *
- * The ARM-driven implementation we use here is short on subtlety,
- * and actually requests a full barrier from the compiler and the CPU.
- * The only difference between acquire and release is in whether they
- * are issued before or after the atomic operation with which they
- * are associated.  To ease the transition to C/C++ atomic intrinsics,
- * you should not rely on this, and instead assume that only the minimal
- * acquire/release protection is provided.
- *
- * NOTE: all int32_t* values are expected to be aligned on 32-bit boundaries.
- * If they are not, atomicity is not guaranteed.

- * Basic arithmetic and bitwise operations.  These all provide a
