You can: Remove/disable package kit. Do manual updates when you feel like it. Reboot when you want to.
That's what I do. The last thing I want is several minutes of waiting around for the computer to shutdown or startup when I don't want to be waiting around. I'll do updates when I've got free time to waste.
Which is what I (the OP) asked about, and have now done. I don't use the Gnome software application for anything, so have disabled its underlying packagekit.
It's irrelevant now for me, but I will note that this runaway CPU-usage thing has just come up in the past week or 10 days, so wonder if something has changed in packagekit?
And, FWIW, I fought and lost my first UNIX/Windows battle 30 years ago. sorry to have crossed into this No Man's Land once again...
