Again, subject is wrong.
Also, I actually think you should avoid using the word "relax", since
that actually has a separate meaning for the atomics, and it is *not*
using those relaxed semantics, and they wouldn't work anyway.
So you might as well just say something like
"locking: use acquire/release semantics"
or similar. Ok?
