I believe JSR-166e (JDK8 and onwards) mostly removed the concept of
concurrency level from ConcurrentHashMap (while it's still there in some
constructors to confuse things). I recall some tests showing that the
difference in footprint between CHM and regular HashMap/Hashtable is now
negligible even for empty, default-initialized instances.
