Bug description:  Setting MYSQLI_OPT_CONNECT_TIMEOUT does not seem to have an effect on timeout

Description:
------------
I have a script that attempts to contact/query an MySQL server on a LAN.
If the server is available, the script runs successfully. If the MySQL
server is offline, however, the script hangs along with the browser session
indefinately. This is despite MYSQLI_OPT_CONNECT_TIMEOUT being set to 5
seconds.

Specifically, the script below hangs when "$mysqli->real_connect" is
executed

Looking for a way to timeout connection attempt.

Running VC9 x86 Thread Safe 5.3. Default mysqli/mysqlnd php.ini settings.

The code below worked fine in the past in the same scenario on version
5.2.8.

Reproduce code:
---------------
$mysqli = mysqli_init();
if (!$mysqli) exit(1);

if (!$mysqli->options(MYSQLI_OPT_CONNECT_TIMEOUT, 5)) {
    exit(1);
}

if (!$mysqli->real_connect('localhost', 'my_user', 'my_password',
'my_db')) {
    exit(1);
}


Expected result:
----------------
Quit in around 5 sec with an code 1 if MySQL is offline.

Actual result:
--------------
Script hangs indefinately and so does a browser session through which the
script is invoked. After some time (e.g. 2-5 min) the following is logged
in php_errors.log:

[23-Oct-2009 00:48:26] PHP Warning:  mysqli::real_connect(): [2002] A
