For the duration of the conversation?

I.e., once you see the last packet of the conversation, it's not  
needed in order to correctly re-dissect any of the packets in the  
conversation?

(BTW, keeping a small data structure around as long as a capture file  
is open, if that's necessary in order to correctly re-dissect a  
packet, is OK - remember, once the first pass over the packets in a  
capture is complete, any packet in the capture can be accessed in any  
order at any time, so, once the first pass is done, there is *no*  
guarantee that, if packet N of the capture is being dissected, packet  
N-1 of the capture was the packet dissected immediately before that.)
