So are kspread's files zipped, and it still helps. I was more thinking of 
zipping up the undo tiles (maybe from the second generation, i.e, as soon as 
a new undo command is added, start compressing the tiles associated with the 
earlier command in a thread. It's something I want to experiment with anyway.
