Description:
------------
Seeking after an OutOfBoundException doesn't work without call of rewind.
With php < 5.3 it works as expected.

Test script:
---------------
$it = new ArrayIterator(array('zf9396', 'foo', null));
$it->rewind();

try {
    $it->seek(3);
} catch (OutOfBoundsException $e) {
    var_dump($it->key());
    $it->seek(0);
    var_dump($it->key());
}


$lit = new LimitIterator($it, 0, 10);
try {
    $lit->seek(3);
} catch (OutOfBoundsException $e) {
    var_dump($lit->key());
    $lit->seek(0);
    var_dump($lit->key());
}



Expected result:
----------------
NULL
int(0)
NULL
int(0)

Actual result:
--------------
NULL
int(0)
NULL
NULL
