Which existing Atomic* classes? I take it you mean the field updaters and
not AtomicInteger and friends. The biggest issue with field updaters is
their performance, for me. I take it you mean something else by "costs"
though? Having to specify the target (field) as a string is annoying, and I
do wish there was a way javac could assist there. VH is no worse in this
respect, but also no better.
