So, am I right that if you have a very well-done pack (such as gcc's), 
you might want to repack in two phases:

- first discarding the old deltas and using a small window, thus 
producing a bad pack that can be repacked without humongous amounts of 
memory...

- ... then discarding the old deltas and producing another 
well-compressed pack?
