thanks for the hint.
i understand, but it does not solve the problem here.

i tuned the service_start() from
/lib/functions/service.sh like this:

service_start() {
        {
        echo
        echo "service_start: $@"
        echo "envsize: $( set | wc -c )"
        network_flush_cache
        echo "envsize_cleaned1: $( set | wc -c )"
        uci_load %
        echo "envsize_cleaned2: $( set | wc -c )"
        set
        } >>/tmp/FOO

        service -S "$@"
}

and still have ~8k vars after 'envsize_cleaned2:'
when starting up /etc/init.d/olsrd (there is no 
change after running 'uci_load %'.

bye, bastian
