PHP Bug Type: Documentation problem
Bug description: Add warning about session on the documentation page for Program Execution

Description:
------------
I'm referring to the "bug" descriped here :
http://bugs.php.net/bug.php?id=10675&edit=1 . I would recommend that you
add a warning on the "Program Execution Functions" documentation page
which basically advises the programmer to close any open session before
calling exec() or other related functions as otherwise the PHP script may
hang!

Reproduce code:
---------------
session_start();
exec('ls');

// Save this, open the page in a browser and reload repeatedly. After
several successful reloads, the page will just hang

Expected result:
----------------
nothing, the correct code seems to be:

session_start();
/*
..... code ...
*/
session_write_close();
exec('ls');
@session_start();

// There's no locking in this code
