Feature request: rate limited queue about async

[peritus]

if (condition_met) {
  q.push(task(req));
} else {
  tell_user_we_are_sorry(req);
}

should do the trick, or am I missing something ?

For simple cases there's the throttle function in underscore.js, but for actual production use accessing an API having the async module keep track of API calls in memory wouldn't scale to multiple processes, so I think it would be limited in application. I don't think we should look to include this in async at the moment.
