Description:
------------
unset( $GLOBALS['foo']); unset only global variable, not variables that
REFERED to global variable

How we can unset global variable with all referenced variable using
unset() function? Do we must user assign to null?

Reproduce code:
---------------
<?php
function a( &$foo) {
$foo = 'ok';
b( $foo);
var_dump( $foo);
}

function b( &$foo) {
$foo = 'not ok';
unset( $GLOBALS['foo']);
}

global $foo;
$foo = 'global';
a($foo);
var_dump( $foo);

?>

Expected result:
----------------
NULL NULL

Actual result:
--------------
string(6) "not ok" NULL
