But the construction of @Contended has nothing to do with atomics,
right? (Yes, the sanest use case is to protect atomically-updated
fields.) "Nanny-state folks" would naturally presume annotating the
plain field with @Contended will turn all operations on that field into
atomics :)

Alternatives:
 java.util.concurrent.hints.Contended
 java.util.concurrent.expert.Contended
 java.util.concurrent.unsafe.Contended
 java.util.concurrent.herebedragons.Contended :)

I think the high-level annotation is already good.
