You are absolutely correct: there are times, e.g., that drinking coffee is "more
important" to me than say, replying to e-mail. However I don't think that Haskel

Meanwhile I do not know of a tool that schedules rpm builds efficiently. I'd be happy
to be wrong.
See the build scheduler for the Hurd in NixOS for what I was referring to
