Per Johan's last mail, some kind of application icon might work well
enough for that (similarly for symlinks, etc).

For the case where you want to say "here, templating engine, is some
output I want to send verbatim for the user", kid doesn't trust you and
parses what you give it to make sure.  The revision view for a change
that touches every line of a 10K line file does this ~30k times which
just takes ages and ages (several minutes).

There are other pages and situations where the performance of Bazaar
could be better (making 'bzr log -v -r -20..' super fast would be really
nice for loggerhead), and loggerhead doesn't always help itself (calling
repository.get_revisions with a list of 100 revisions on a tree the size
of launchpad isn't too friendly).
