Don't think much survived from v2 - this is a fresh start anyway. Perhaps old patch 2 the same, but beyond that a different approach to remove recursive read/write locks and replace with using rwlock read/write where the write's are in very tight confines.
I've run the changes through avocado with success. There were some really strange deadlocks along the way - even causing libvirtd to go defunct. There's a lot of strange ways to use/access the nwfilters.
