Ok cool no prob

Just tried some weird cases and think that there is an another problem. The
self referencing of object don't work. The serialization data (var_hash) is
not the same (you can't use unserialized references...). Try this:

$n = gmp_init(42);
$n->obj = $n;
var_dump(unserialize(serialize($n)));

(you will get really cool animation when you run it... :) )

My patch is not match better as I am getting segfault. :) I will probably
have to do a bit more testing... :)
