I'm giving a bit more love to my git-exports these days and I see strange
anomalies...
https://ci.inria.fr/pharo/job/Pharo-2.0-Git-Export/buildTimeTrendPharo version 20458 and starting from 20463, the export takes a factor 6 longer.
I did not investigate further much further, so I will wait until I catch up
to the latest Pharo release.
