-----------------------------------------------------------------
Again, the 0.94 patch just puts back HBASE-5533 style measurements, not
reinventing *proper* accounting. Edit: I should say makes them not mostly
useless.

> HBASE-5533 metrics miss all operations submitted via MultiAction

> A client application (LoadTestTool) calls put() on HTables. Internally to the
> HBase client those puts are batched into MultiActions. The total number of
> put operations shown in the RegionServer's put metrics histogram never
> increases from 0 even though millions of such operations are made. Needless
> to say the latency for those operations are not measured either. The value of
> HBASE-5533 metrics are suspect given the client will batch put and delete ops
> like this.
> I had a fix in progress but HBASE-6284 messed it up. Before, MultiAction
> processing in HRegionServer would distingush between puts and deletes and
> dispatch them separately. It was easy to account for the time for them. Now
> both puts and deletes are submitted in batch together as mutations.
