There are a couple of things we can do here beyond speeding up and
caching annotations.  I think there are already Loggerhead bugs for
them:

 * don't show annotations if the person just wants to see the content
of the file
 * load the text first then load the annotations through asynchronous javascript
 * as John mentioned above, just have a predictable URL for the
current version of a file
<https://bugs.edge.launchpad.net/loggerhead/+bug/322295>
 * give a better message if we do fail
