> Profiling of ThriftServer here at SU has indicated that the call 
> ThriftUtilities.rowResultFromHBase() is quite inefficient.  It first calls 
> Result.getRowResult() which is inefficient and slow. Instead by 
> reimplementing to create the TRowResult (the thrift return type) straight 
> from the KeyValue[] array the performance boost is substantial, reducing time 
> serializing the results.  In my profiling the time spent in scannerGetList() 
> went from 1100ms to 108ms on similar test runs.
