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?
I'm not entirely certain what's triggering this, but I have identified that
removing a couple of sha1 checks cuts 1s out of 15s for me. This makes me
wonder whether it's worth looking into a faster sha1 implementation.
