class Concurrent::ThreadSafe::Util::Striped64::Cell
Padded variant of AtomicLong supporting only raw accesses plus CAS. The value
field is placed between pads, hoping that the JVM doesn't reorder them.
Optimisation note: It would be possible to use a release-only form of CAS here, if it were provided.
