Description:
------------
The code below works fine with PHP 5.2.6 (and earlier), but not with the unreleased PHP 5.2.7 and PHP 5.3.0:

    892 $handle = @fopen($url, 'r');
    893
    894 if (!$handle) {
    895     throw new RuntimeException(
    896       'Could not connect to the Selenium RC server.'
    897     );
    898 }
    899
    900 stream_set_blocking($handle, 1);
    901 stream_set_timeout($handle, 0, $this->timeout);
    902
    903 $info     = stream_get_meta_data($handle);
    904 $response = '';
    905
    906 while ((!feof($handle)) && (!$info['timed_out'])) {
    907     $response .= fgets($handle, 4096);
    908     $info = stream_get_meta_data($handle);
    909 }
    910
    911 fclose($handle);

The code above hangs with PHP 5.2.7 and PHP 5.3.0 in line 906 as shown using Xdebug's tracing:

    fopen() Driver.php:892
    stream_set_blocking() Driver.php:900
    stream_set_timeout() Driver.php:901
    stream_get_meta_data() Driver.php:903
    feof() Driver.php:906
    fgets() Driver.php:907
    stream_get_meta_data() Driver.php:908
    feof() Driver.php:906

The second feof() call above hangs.

Changing the loop to

    while (!$info['eof'] && !$info['timed_out']) {
        $response .= fgets($handle, 4096);
        $info = stream_get_meta_data($handle);
    }

fixes the problem. This means a difference between feof() and $info['eof'].
