I agree with Ben.Â I think it is admirable to want to find a better way
to do things but we have tried numerous different approaches in Cinder
to try and avoid the crunch at the end but the fact is that it appears
that everyone procrastinates until the last minute.Â It seems to be one
of the problems of being an open community where people don't always
have full time to work on development.
