Yes, sorry, I think I have given the impression that I have had no way
of working around this; I do, and I have. It is just an inconvenience.

Usually what I do is that when I come upon a package that will take a
long time to build, I kill the upgrade, pass the package to
`--do-not-upgrade`, and continue.

Yes, I think it would be better for users, and on Guix's infrastructure.
