Bug description:  socket_read() fails to return empty string

Description:
------------
According to documentation:

"Note: socket_read() returns a zero length string ("") when there is no
more data to read."

This does not seem to be the case on my installations:
PHP 5.3.0 WinVista
PHP 5.2.11 WinVista
PHP 5.2.11 FreeBSD
PHP 5.2.10 WinVista
PHP 5.2.9 WinVista

socket_read() just hangs.

Reproduce code:
---------------
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
$connection = socket_connect($socket, 'news.giganews.com', 119);

$response = '';
do {
  $recv = '';
  echo "START READ\n";
  $recv = socket_read($socket, 512);
  echo "END READ\n";
  var_dump($recv);
  if($recv != '') {
    $response .= $recv;
  }
} while($recv != '');

echo 'OUTPUT: ' . $reply;

Expected result:
----------------
START READ
END READ
string(23) "200 News.GigaNews.Com
"
START READ
END READ
OUTPUT: 200 News.GigaNews.Com

Actual result:
--------------
START READ
END READ
string(23) "200 News.GigaNews.Com
"
START READ
