title: How are ClientBundles generated? Should I cache or recreate?
body: <p>The particular case I am looking at is with a client bundle used in multiple UiBinders. The client bundle is included in a ui:with tag. Is a new client bundle being generate for each one, and if so what are the performance implications?</p>
  
  <p>I can cache the ClientBundle with the @UiField(provided=true) annotation, is this a good idea?</p>
