And now you know one of the reasons we have no true progress bar.

Another reason is that it would be relatively expensive to calculate, 
since the total _size_ is not known beforehand (remember, the pack is 
calculated on the fly).

Yet another reason is that all estimates there are unstable by nature: the 
load of the server, the net load, the load of the client, the speed of 
packing and unpacking, and the luck if deltas can be reused, are all 
contributors to this unstability.
