spawn-fcgi -u -g disable php from making core dump

[moo]

with setuidgid:

ulimit -c 0
exec setuidgid user /usr/bin/php-cgi -b 1026

it will generate core even after setuidgid, and it is safe to do so, because the whole php-fcgi process data belongs to the child from the begining of process.

but with spawn-fcgi

ulimit -c 0
exec /usr/bin/setuidgid traviantoolbox /usr/bin/spawn-fcgi -p 1027 -f /usr/bin/php-cgi  -C 4

php will not generate a core file on segv.

not verified, as it was not me but renchap that got the problem.
