I've seen this information of 100 content processes in a couple places but
i haven't been able to find the rationale for it. How was the 100 number
picked? Would 90 prevent a release of project fission?
How will the rollout happen?
   Will the rollout happen progressively (like 2 content processes soon, 4
soon after, 10 some time after, etc.) or does it have to be 1 (current
situation IIUC) then 100?

How often is this code run? Is there a place to find the daily output of
this tool applied to a nightly build for instance?

Thanks again,
