We'll the current process certainly places a lot of emphasis on the
"finishing" part. You have commit fests that nominally account for 50%
of development time, and then beta, RC, limbo, backbranch releases -- I
blogged about this a while ago, if you follow all these guidelines and
encouragements, you are left with all of about 20 days per year for
discussion, collaborative planning and coding. Which is obviously
silly, which is why the process breaks down. People do other things as
commit fests fade out, but they subconsciously fear they will get the
stink for it, so public discussion and planning is effectively stifled.

I think we should put less temporal emphasis on the finishing part, but
use the time better. I would imagine one commit fest per month, but
it's only a week long. Then everyone can really concentrate on the
commit fest, people get faster feedback, but there is ultimately more
time to do other things. Something to think about.
