a: don't need to load a whole new instance of Ethereal (which is far more than we need to do) as this takes it's time. A small tool (the Win32 exe seems to become ~200kB instead of the xMB "monster" Ethereal is) can probably be loaded much faster (hmmm, with todays operating system caching I'm not too sure about this) 


Not valid on unix/linux


Not sure what you mean with this ...
What he means is that a modern UNIX/Linux system shares all the pages, so the fact that you run the same program twice does not cost you much. And, with Copy on Write, even pages that are modified in each of the images don't cost much. 

I suspect that Windows does as well.
