Looks good to me.  Minor comments below.

    Should this be public?  Isn't it just used internally?

    Is this a copy?

    You were going to replace these w/ something from guava (or is this it?)

    Same here

    This creates new Map, pass in Map.Entry instead?

    I hate that this is even an option (smile)

    w can never be null here?  (There was null check previous)

> HBASE-2283 removed bulk sync optimization for multi-row puts

> previously to HBASE-2283 we used to call flush/sync once per put(Put[]) call 
> (ie: batch of commits).  Now we do for every row.  
> This makes bulk uploads slower if you are using WAL.  Is there an acceptable 
> solution to achieve both safety and performance by bulk-sync'ing puts?  Or 
> would this not work in face of atomic guarantees?
> discuss!
