[HttpClient] CurlHttpClient idle timeout

[kbond]

Symfony version(s) affected

4.4.34

Description

After upgrading from 4.4.33 to 4.4.34 CurlHttpClient is giving me "Idle timeout reached for..." errors when requesting any url.

How to reproduce

$response = HttpClient::create()->request('GET', 'https://symfony.com');
dd($response->getStatusCode()); // hangs then throws:

In ErrorChunk.php line 64:
                                                               
  [Symfony\Component\HttpClient\Exception\TransportException]  
  Idle timeout reached for "https://symfony.com/".

Possible Solution

Reverting #43961 fixed the issue for me.
