* (string, default: php-requests/$version)
* - `follow_redirects`: Should we follow 3xx redirects?
* (boolean, default: true)
* - `redirects`: How many times should we redirect before erroring?
* (integer, default: 10)
* - `blocking`: Should we block processing on this request?
* (boolean, default: true)

/**
* Send multiple HTTP requests simultaneously
*
* The `$requests` parameter takes an associative or indexed array of
* request fields. The key of each request can be used to match up the
* request with the returned data, or with the request passed into your
* `multiple.request.complete` callback.
*
* The request fields value is an associative array with the following keys:
*
* - `url`: Request URL Same as the `$url` parameter to
* {@see \WpOrg\Requests\Requests::request()}
* (string, required)
* - `headers`: Associative array of header fields. Same as the `$headers`
* parameter to {@see \WpOrg\Requests\Requests::request()}
* (array, default: `array()`)
* - `data`: Associative array of data fields or a string. Same as the
* `$data` parameter to {@see \WpOrg\Requests\Requests::request()}
* (array|string, default: `array()`)
* - `type`: HTTP request type (use \WpOrg\Requests\Requests constants). Same as the `$type`
* parameter to {@see \WpOrg\Requests\Requests::request()}
* (string, default: `\WpOrg\Requests\Requests::GET`)
* - `cookies`: Associative array of cookie name to value, or cookie jar.
* (array|\WpOrg\Requests\Cookie\Jar)
*
* If the `$options` parameter is specified, individual requests will
* inherit options from it. This can be used to use a single hooking system,
* or set all the types to `\WpOrg\Requests\Requests::POST`, for example.
*
* In addition, the `$options` parameter takes the following global options:
*
* - `complete`: A callback for when a request is complete. Takes two
* parameters, a \WpOrg\Requests\Response/\WpOrg\Requests\Exception reference, and the
* ID from the request array (Note: this can also be overridden on a
* per-request basis, although that's a little silly)
* (callback)
*
* @param array $requests Requests data (see description for more information)
* @param array $options Global and default options (see {@see \WpOrg\Requests\Requests::request()})
* @return array Responses (either \WpOrg\Requests\Response or a \WpOrg\Requests\Exception object)
*
* @throws \WpOrg\Requests\Exception\InvalidArgument When the passed $requests argument is not an array or iterable object with array access.
* @throws \WpOrg\Requests\Exception\InvalidArgument When the passed $options argument is not an array.
