Description:
------------
I have the same problem as in bug:

http://bugs.php.net/bug.php?id=47640

In php 5.2.10 has not been solved




Reproduce code:
---------------
<?php

session_start();
while (true) { $i *= 2; }

?>


Expected result:
----------------
I can strace apache/php processes seeing that there is a PHP script
doing flock() on a file, the process never returns.

PHP session handler should have some timeout and/or old file locks
should be hard-broken.


Actual result:
--------------
Forever-Hanging php processes.
