Setting CURL option via Service Container for Guzzle

Question

I need to set CURLOPT_TCP_NODELAY CURL option, but the problem is that I don't know how to do it using Service Container of Sf2.

Here is how Guzzle is injected now:

services:
    user.user_manager:
        class: Foo\UserBundle\Model\UserManager
        arguments:
            - @guzzle.client

But I need to add CURLOPT_TCP_NODELAY as well.

Plain PHP example:

$guzzle = new \Guzzle\Http\Client(null, array(
    'curl.options' => array(
        'CURLOPT_TCP_NODELAY' => 1
)));
