Description:
------------
Global variables are not shared between threads, as real threads would do.

Test script:
---------------
<?php
class Test extends Thread {
    public function run() {
        $GLOBALS['x'] = 'bar';
    }
}

$x = "foo";

echo $x;
$thread = new Test();
echo $x;

$thread->start();
$thread->join();
?>


Expected result:
----------------
foobar

Actual result:
--------------
foofoo

oups... uploaded the buggus testscript example....

fixed one:

<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');

class Test extends Thread {
    public function run() {
        $GLOBALS['x'] = 'bar';
    }
}

$x = "foo";

echo $x;
$thread = new Test();

$thread->start();
$thread->join();
echo $x;
?>

however the problem remains the same.

threads are not supposed to have access to global variables.
