For another sample with more IDRs on a 4yo linux system with 6 cores,
there is actually a decrease. The sequence or system also scales
poorly: 6 cores yields less than 3x speedup compared to a single

The change makes sense by itself, but it doesn't seem worth it. I'd
still like to see if Mickaël can provide more meaningful numbers.
