Managing how you do your updates and maintenance is a personal workflow. I either do it as soon as I get to the studio, and start it while I go to the bathroom, take off my coat, turn on the rest of the lights, and pop open my laptop to look at any notes while it processes. Or I do it at the end of the night and start it downloading while I go to the bathroom, turn off some lights, put on my coat...you get the idea.
I'm in the middle of finishing a record, so it's pretty easy to bust out some mixes, and start updating SONAR while I upload to Soundcloud and listen to them on my reference monitors. As long as updates don't require a restart I can work in another program entirely while SONAR updates in the background. Easy peasey.
