Hi Joel,

I originally implemented the -z mode to get Snort to ignore 
stick/snot/etc attacks by only alerting on TCP events if the session 
had been established first.  It's probably superfluous at this point 
since we have the flow keywords available for the rules language now.  
In fact, we'll probably pull it out after 2.2 goes out the door...
