AtomicLongMap.incrementAll(Iterable<K>)

[GoogleCodeExporter]

Of course, this would increment the value for each key passed in, as many times 
as the key was passed in, and of course there would be a fast path if the 
iterable is a multiset.

I don't have a list of motivating real-world use cases to provide yet; I just 
noticed that the recurring "how do I convert a multiset into a map of counts?" 
question could potentially be addressed by this.

Today:

    Map<String, Integer> result = new HashMap<>();
    for(String element: multiset.elementSet()) {
        result.put(element, multiset.count(element));
    }
    // return ImmutableMap.copyOf(result); ?

Tomorrow?

    AtomicLongMap<String> result = AtomicLongMap.create();
    result.incrementAll(multiset);
    // return ImmutableMap.copyOf(result.asMap()); ?
