--------------------------------
bq. If this JIRA is easy and can get us there immediately....
Lets see. Taking a guess, transactions x-region would be more work than
index-colocated-inside-region-with-data. But lets see.

> Given that local index updates happen on the same region server as the data
> updates, we should be able to make them transaction: either both the data and
> index updates succeed, or neither of them do. I seem to remember [~lhofhansl]
> mentioned that the all or none behavior of HRegion.mutateRowsWithLocks()
> could be emulated across tables if you knew that the mutations were all local.
