Found in master:3a5e46b6ed483e43251da7e328b9299189997722 When a build is in progress, we show a progress bar (in the 'all builds' page and in the corresponding 'project builds' page). Currently, the progress bar only updates when you refresh the page. It would be good to update the progress bar without requiring a page refresh.
The page does refresh via Ajax calls, for the project builds page; the all builds page still needs a page refresh.
