There is some internal curl error (CURLE_FAILED_INIT) when you are trying to use just copied curl handle in curl_multi_add_handle(). I have checked the same problematic PHP code but with little difference: instead of creating curl’s copy I have used the original one (template). As I expect code works without any error. I think curl_multi_* along with curl_copy_handle() is still raw and needs some improvements.

You can use it for some kind of templates: 

Hmm I don't have a problem with this, using PHP 5.2.5 libcurl 7.16.3 maybe it's been fixed ...
I am m having trouble getting curl_copy_handle to copy all the curlopts across though...
  protected function curlMultiPrime(array $reqArr){
    // Store the request array so we can reinitialise the multi handle
    $this->reqArr = $reqArr;
    // Close existing curl uni handles
    $this->closeMultiCurlUniHandles();
    foreach($reqArr as $curlConf){
      if(!($curlConf instanceof curlConfRequest ))
        throw new curlConfException('All objects passed to configure requests must be instances of curlConfRequest.',curlConfException::CURL_INVALID_CONF_OBJ);
      if(!$cch = curl_copy_handle($this->curlHandle)){
        throw new curlException('Failed to clone template curl handle.',$this->curlHandle);
      }else{
        curl_setopt_array($cch,$curlConf->getCurlOpts());
      }
      if(curl_multi_add_handle($this->curlMultiHandle,$cch) === 0){
        $this->curlUniHandleRef[] = $cch;
      }else{
        throw new curlException('Failed to add curl handle to multi stack.',$cch);
      }
    }
  }
