fak2.php:
----------
<?php
class SomeClass
{

}
if( !isset( $someVar ) )
{
        $someVar = new SomeClass();
        session_register("someVar");
}
?>

f2.php:
-------
<?php
session_start();

require_once( "fak2.php" );

echo session_encode();
?>

load f2.php 3 times.  It hangs.  Don't know if this is a repeat php.net stopped responding while I was searching through old bugs.  If this has been fixed, or I am doing something wrong, please email me.
