filelock generate too many open files

[Felixxxlz]

I have to refresh iptable frequently, on suse11 which iptables version is iptables v1.4.16.

It will open filelock /var/run/xtables.lock each time when I do the update, but the filelock wasn't really closed, after a few days it shows too many files open and failed. How could I close these filelocks?

Hi @Felixxxlz , it seems that because you use a version of iptables <1.4.20 that does not support locking, you are failing over to an emulated filelock in go-iptables: e785537#diff-090f71c532949e591510a0220651f3e5

I have proposed a patch that might help, but I think there might need some more work as discussed here #64 - I can eventually propose a patch if the behaviour I'm proposing gets the thumbs up by a maintainer 👍
