Bug Description
While using MAAS, I noticed that chromium was using 100% CPU, with only MAAS 2.7 rc7 open in a tab, being almost completely unresponsive. Can't really say what triggered it. I was clicking around a bit in the UI, selecting which images to sync, looking at the controllers pages, deploying machines, etc.
Now it's settled down, and I see this in the JS console:

I also see this further up in the JS console a few times:
