--------------------------------------

bq. Does this mean that b885130 has an issue?
I'd say the difference here is in the noise.
One thing to keep in mind is that I'm running {{scanRange100}}, while JM
reported the issue in FilteredScanTest. To run that test on this dataset, I'll
need to add some new versions of the filtered test that limit scan range, or
make the existing scanRange tests accept a filter as an arg.
