firewall3 isn't holding iptables lock

I was first thinking that my missing iptables rules are related to the bug
FS#943
. But it looks like firewall3 is not holding the iptables lock via the option “-w”. This is unsafe because multiple iptables process may try to change a table at the same time and thus overwrite the final results of another iptables process.
The -w functionality for iptables-restore can be found in
