Is anyone able to reproduce on previous versions such as those I've
found it on?  

If so should the documentation be updated to note this issue?

Can't reproduce on 5.2.9.

I'm sorry, building your latest source to test this further is not
something I can do.  I'm hopeful that you have enough developers that
you can use the test case I provided to reproduce this yourselves.

Thanks

Description:
------------
Placing flock() calls within a function seems to result in blocking
regardless of the operations specified.  The same exact code outside a
function behaves correctly.

This bug report wouldn't let me select the PHP version I'm running. 
Wasn't an option

Reproduce code:
---------------
http://alishabeth.com/lock-test.php.txt

Reproduced in the following builds:
$ php -v
PHP 5.1.6 (cli) (built: Apr  7 2009 08:00:18) 
Copyright (c) 1997-2006 The PHP Group
Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies
    with eAccelerator v0.9.5.2, Copyright (c) 2004-2006 eAccelerator,
by eAccelerator


$ php -v
PHP 5.2.6-3ubuntu4.1 with Suhosin-Patch 0.9.6.2 (cli) (built: Apr 23
2009 14:37:14) 
Copyright (c) 1997-2008 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies
    with Xdebug v2.0.3, Copyright (c) 2002-2007, by Derick Rethans


Expected result:
----------------
Using the function always blocks

Actual result:
--------------
Flock should behave correctly within the function
