Operating system: Solaris 10
PHP version:      5.2.9
PHP Bug Type:     *Web Server problem
Bug description:  File descriptor leak

Description:
------------
mod_php contains a potential file descriptor leak on Solaris 10 when 
script executes "exit()".

Reproduce code:
---------------
<?php exit(0); ?>

The change in behavior is due to the addition of HAVE_BROKEN_GETCWD for
Solaris 10. In php_execute_script, a file descriptor is opened to hold the
current working directory, but is not closed in the case where php code may
not return to this function after executing a script. mod_php isn't aware
of the resource that was allocated and not freed.

Expected result:
----------------
Normally web server runs for days without resource trouble. In the 
case where a PHP script does an "exit(0)", the web server will run 
out of file descriptors and will need restarting.
