docstring: Sends multiple requests concurrently and returns an array of responses
  and exceptions that uses the same ordering as the provided requests.
  
  IMPORTANT: This method keeps every request and response in memory, and
  as such, is NOT recommended when sending a large number or an
  indeterminate number of requests concurrently.
  
  @param ClientInterface $client   Client used to send the requests
  @param array|\Iterator $requests Requests to send concurrently.
  @param array           $options  Passes through the options available in
  {@see GuzzleHttp\Pool::__construct}
  
  @return array Returns an array containing the response or an exception
  in the same order that the requests were sent.
  @throws \InvalidArgumentException if the event format is incorrect.
