Comment (by tardyp):

 The way it is done allows not only to cache, but also to manage the
 updates automatically. Several attempt to listen to the same builds will
 not only avoid to create http request to the data, but also prevent the
 registering of update events on that build.

 This results in a very big impression of speed. Once build page has been
 seen once, you can go back instantly. updates will even work in the
 background, as the events are unregistered only few minutes after the last
 consumer as unbind the data.
