HttpRequestPool in PECL::HTTP

I just checked in a first working version of HttpRequestPool into CVS.
It's curl_multi that's doing its job underneath and is used tp send several HttpRequests at once.

<?php

$urls = array(
    'http://www.php.net/',
    'http://pear.php.net/',
    'http://pecl.php.net/'
);

$pool = new HttpRequestPool;
foreach ($urls as $url) {
    $pool->attach(new HttpRequest($url, HTTP_METH_HEAD));
}

try {
    $pool->send();
    foreach ($pool as $r) {
        $status = $r->getResponseCode();
        printf("%-20s is %sn",
            $r->getUrl(),
            $status == 200 ? "ALIVE" : "NOT OK ($status)"
        );
    }
} catch (HttpException $ex) {
    echo $ex;
}
?>
