    https://github.com/apache/tinkerpop/pull/478
  
    After actually thinking about this, the type of future returned will depend 
on the underlying `RemoteConnection` implementation.  A call to the 
method`promise` will cause a `(async)traversal_strategy` to call `apply`, the 
result of this depends on the underlying remote connection, and all the GLV has 
to do is pass the returned futures along to the end user. Therefore a Tornado 
based driver would return a `tornado.concurrent.Future` etc. etc. Make sense? 
Or am I missing something...?

> [~mbroecheler] had the idea of adding a {{Traversal.async()}} method. This is 
> important for not only avoiding thread locking on a query in Gremlin, but 
> also, it will allow single threaded language variants like Gremlin-JavaScript 
> to use callbacks for processing query results.
> {code}
> Future<List<String>> result = 
> g.V().out().values("name").async(Traversal::toList)
> {code}
> {code}
> Future<List<String>> result = g.V().out().name.async{it.toList()}
> {code}
> {code}
> g.V().out().values('name').async((err,names) => {
>   // I don't know JavaScript, but ...
>   return list(names);
> }) 
> {code}
> ...
