• [ ] #2804
• [ ] Apply constraints to limit usage on a per-zone basis
• [ ] Use this information as a factor in sled selection for services and instances
• [ ] Add metrics to periodically monitor true CPU and RAM utilization by services within the sled

1700 is a similar issue, but for disk space

Latest on this:

• RFD 413 on memory governance is ready for one last once-over before publishing
• Once it is published I will create a project plan for the work it describes
• I'll then create issues to track those work items
• We also need an RFD talking about CPU governance; I'm undecided as to whether to do that in RFD 395 or write something else (leaning very vaguely toward the latter). I expect that RFD to be less complex and believe that a good deal of the work we do for memory governance will be extensible to CPU governance (provided we play our cards right).
