Is it possible to return work without fetching new work? This is something I would occasionally like to do when I need to quit processing on a machine for an extended duration. Ideally, I would process everything already in the work buffer but just not fetch new work.

I can get close by setting my work buffer to 0.0 days and waiting until everything to the last batch of WUs has been completed, but I can't seem to then tell it "complete this without getting more".

Is there a way to do this? I don't like the idea of leaving WUs dangling for resubmission to someone else a week later when I know today that they'll never be completed.
