/* We want to achieve __ATOMIC_SEQ_CST semantics here. See

 * operations, that means performing an *acquire*:
 * > A load operation with this memory order performs the acquire operation on
 * > the affected memory location: no reads or writes in the current thread can
 * > be reordered before this load. All writes in other threads that release
 * > the same atomic variable are visible in the current thread.
 *
 * “no reads or writes in the current thread can be reordered before this load”
 * is implemented using a compiler barrier (a no-op `__asm__` section) to
 * prevent instruction reordering. Writes in other threads are synchronised
 * using `__sync_synchronize()`. It’s unclear from the GCC documentation whether
 * `__sync_synchronize()` acts as a compiler barrier, hence our explicit use of
 * one.
 *
 * For store operations, `__ATOMIC_SEQ_CST` means performing a *release*:
 * > A store operation with this memory order performs the release operation:
 * > no reads or writes in the current thread can be reordered after this store.
 * > All writes in the current thread are visible in other threads that acquire
 * > the same atomic variable (see Release-Acquire ordering below) and writes
 * > that carry a dependency into the atomic variable become visible in other
 * > threads that consume the same atomic (see Release-Consume ordering below).
 *
 * “no reads or writes in the current thread can be reordered after this store”
 * is implemented using a compiler barrier to prevent instruction reordering.
 * “All writes in the current thread are visible in other threads” is implemented
 * using `__sync_synchronize()`; similarly for “writes that carry a dependency”.
