that suggests one is tracking segmentation boundaries, in which case 
wouldn't one be using conservation of packets heuristics rather than 
conservation of bytes heuristics - packet counting rather than byte

[istr that was part of the issue when Linux tried to implement the 
byte-counting ABC RFC in their packet counting stack...]
