> Emit when we roll master proc WAL so can see when they happen. Want to 
> correlate instances of corruption w/ events on Master. Currently hard to do 
> on  a server where log-level is INFO (default for many deploys).
> Also, we log STUCK regions every 5 seconds. If a bundle of regions get stuck, 
> we can log so frequently, we roll away where the problem happened so lose the 
> chance to debug. Let me fix that too....
> Need both debugging instances of parent issue.
