Unfortunately not, as libevent was removed from FPM in PHP 5.3.4, the patch has
to be ported to the new simple mini event library. If you are interested to do
the port and you are familar with C you are welcome, and I can give you a quick
starting point.

I tried to patch php5-5.3.5 with the last offered patch, but it did not work.
Does a patch against the current version exist?
Thanks

Just to be clear, I'm not advocating this solution, just contemplating the
implications.
Hand built disable_functions by sysadmins is not realistic and centralized
maintenance in FPM code (if at all possible) would still require work and be
prone to error.
Running as root is very bad security wise and makes almost every other security
check useless in case of a bug.

- it's very complex to do.
- you have no guarantee that nothing will be forgotten (until a security hole
is found)
- you have to maintain this security layer over the time, adding new functions,
...
- If the sysadm have to list the functions to be forgotten, it will forget some
(by following a buggy how-to -- which are all over the
Internet btw)

I'm sorry, but it's not an option to me. There security checks at kernel level
which must not be gotten arround by code running from userland
(PHP core).
