 * “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

 * 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*:

 * > 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
