Please take a look at http://bugs.php.net/bug.php?id=38915:
[4 Dec 6:43pm UTC] crescentfreshpot at yahoo dot com
Just to add to the dialog, Apache 1.x seems to have tried to address the
issue of leaked FDs itself. http://www.apache.org/dist/httpd/CHANGES_1.3
says:
Changes with Apache 1.3.28
*) Certain 3rd party modules would bypass the Apache API and not
invoke ap_cleanup_for_exec() before creating sub-processes.
To such a child process, Apache's file descriptors (lock
fd's, log files, sockets) were accessible, allowing them
direct access to Apache log file etc. Where the OS allows,
we now add proactive close functions to prevent these file
descriptors from leaking to the child processes.
As far as I understand the above, apache thinks it can know when
[mod_]php does a system-level popen() and cleanup the parent FDs before
exec(). Is that actually possible?

I think that's exactly what FD_CLOEXEC does.

It's not clear that this is an Apache bug. One could argue that mod_php should
use apr_proc_create instead of using exec. See
