hedged (simultaneous) requests #278

It would be great to be able to send multiple simultaneous requests to several urls, but return the fastest response. When it is needed: we have several identical api endpoints, but we need to return the data to the client as quickly as possible. Endpoints can respond at different rates. We send a request to both endpoints, wait for a response from the fastest and return only it. This is an extremely useful pattern in applications where response speed is critical.
