Description:
------------
I serialized a SplObjectStorage instance containing several objects.  After unserialization, the SplObjectStorage object contained nothing.

It doesn't say in the SPL documentation that SplObjectStorage cannot be serialized.

Reproduce code:
---------------
<?php

class test { }

$storage = new SplObjectStorage();

for( $i=0; $i<5; $i++ ) {
     $test = new test();
     $test->example = 'testing'.$i;
     $storage->attach( $test );
}

echo "Before: ".count($storage)."<br>";

$str = serialize($storage);

$storage2 = unserialize( $str );

echo "After: ".count($storage2)."<br>";

?>

Expected result:
----------------
Before: 5
After: 5

Actual result:
--------------
Before: 5
After: 0

Actually this is a feature request. Overloaded objects are typically not serializable even though PHP in theory has everything to allow that.

Works in HEAD now, except for unicode mode. Support in 5.2 might be added as well. The patch at least works.
