I've reproduced the problem - the key thing I was missing is that it
only occurs if every VM is using a different named nwfilter. It they
all use 'clean-traffic' it is fine, but if they use 'clean-traffic-xxx'
where 'xxx' is the name of the VM it deadlocks. This is why I never
spotted it before :-(

Please try out this patch
