Sorry to double-reply, but I thought it worthwhile to note that the time to intern strings via ConcurrentHashMap is measured in the low double-digit nanoseconds on my machine, so this may indeed end up being nontrivial. But I will consider it trivial unless I can measure it to be large.
Wouldn't the more suitable comparison be a weak hash map? Interned strings are still subject to garbage collection, after all.
