> PerformanceEvaluation's 'column' parameter looks broken to me.
> To test:
> 1. Write some data with 20 columns.
> 2. Do a scan test selecting one column.
> 3. Do a scan test selecting ten columns.
> You'd expect the amount of data returned to vary but no, because the read
> side isn't selecting the same qualifiers that are written. Bytes returned in
> case 3 should be 10x those in case 2.
> I'm in branch-1 code at the moment. Probably affects trunk too.
