The system usually gets into a pretty much dead state after a couple of OOMs
of so.   There's also the little fact that prior to that commit, the OOMs
don't happen at all as far as I can tell.

I don't know for certain that the OOMs don't happen on the commits that have
come up good.  Sadly, all I can say is that after running N commits, I haven't
seen an OOM.
