Really? I'm not so sure about that 'great deal' I think right now 
we are only freeing protocol frame data list.

If they want state-less they should probably use tcpdump.

To be honest I don't like option --state-less (it'd be really hard to find),
I'd rather make single pass really state-less (if that's what user expect).
And if user want to do pro dissection -2 must be used anyway.
