(probably not once per character, except in worse case scenarii; in
general, while there is no guarantee that characters be all stuck
together in the data call in the SAX API, it doesn't imply that each
character generates such a call either)

Err... Is this API call done even when the show outline option isn't
enabled? If so, the best solution might be to make sure it isn't called
unless it is enabled, no?
