The progress reporting is fantastic!  It's worth upgrading to darcs2 just 
for that :-)  Although the progress reporting doesn't appear to work quite 
as well on darcs-1 repositories as it does on darcs-2 repositories - is 
that expected?

There are still times when I see nothing happening, for example in the 
unpull test on the GHC repo (see previous messages), the last progress 
message I get is

Reading patches in /64playpen/simonmar/ghc-darcs2 17040

and it sits there for 7-8 seconds before completing.  Does this maybe shed 
any light on why this unpull is 2 times slower than darcs1?
