When kicking off a build, I have to remember to navigate away from the build page because otherwise my CPU will become pegged at 100% and I will be forced to close the tab and re-open.
This was true when I was using Chrome on a Mac, but also true on Windows. My current Chrome version is 53.0.2785.143 m (64-bit).
