Bug#423002: apache: The RLimitCPU directive doesn't act

If you use mod_php this is the intended behaviour. From

http://httpd.apache.org/docs/1.3/mod/core.html#rlimitcpu

"This applies to processes forked off from Apache children servicing
requests, not the Apache children themselves."

So this will affect php only if you use it in cgi mode, not if the php
scripts run in apache with mod_php.
