So should COMMAND/CMS get an option to create a private work unit? And when should this be committed? Presumably another option to do it at every command or at the end.
Don't forget multiple simultaneous COMMANDs; you might get into a situation where left hand is not knowing what right hand is doing. Or are we getting to the point where an entire pipeline should get itself a work unit and make that the default one (if one can)?
