Description:
------------
When you create 2 or more instances of PDO (or derived) with 
ATTR_PERSISTENT you end up with several references to only one 
object.

Reproduce code:
---------------
<?php
class MyPDO extends PDO {}

$bar = new PDO("sqlite::memory:", null, null, array(PDO::ATTR_PERSISTENT => true));
$baz = new MyPDO("sqlite::memory:", null, null, array(PDO::ATTR_PERSISTENT => true));

var_dump ($bar);
var_dump ($baz);
?>

Expected result:
----------------
object(PDO)#1 (0) {
}
object(MyPDO)#2 (0) {
}






Actual result:
--------------
object(MyPDO)#1 (0) {
}
object(MyPDO)#2 (0) {
}

It's fixed "only" in phpng, so let's keep it open until/when phpng gets merged.
