If it's just for the sake of trying one last time, we could just add
--cores=1 to the Guix invocations, or run everything in a single-core
VM.  Wouldn't that have the same effect?

I think you'll probably agree, so I've proactively started another build
on two fresh single-core VMs (using the same procedure I described
earlier, starting from the 1.2.0 installation ISO image).  It'll take a
few days to finish, I'm sure.  Please let me know if you think we need
the patch to run this final experiment.  Otherwise, I'll just report the
results of this latest experiment in a few days' time.
