It seems to be that of the problems with the current version of darcs
that Simon described in this initial email, performance is really the
one major problem that is not addressed by David's new work. At the
same time, GHC developers seem to be the sort of people who know a lot
about how to write fast Haskell programs. So, I am thinking
performance optimisations might quite possibly be the area where we
could help David out most effectively - maybe Don could have a look at
that, too. Does that make sense?
