Review Comment:
I don't think the extra object creation matters in this case and the extra
features of the atomic classes are nice. One thing i just realized was that if
we want to use other Atomic classes like AtomicLong, which would be nice, then
we may not be able to use generics after all as that atomic type needs to be
different and we'd have slightly different code
