Comment (by jbrinley):

 @sc0ttkclark - I'm not quite comfortable saying that 17817.3.patch is
 ready for core, yet. As @wonderboymusic just said, it needs to be more
 performant. If core devs, or anyone else, has suggestions along those
 lines, they would be welcome. It's already improved from 17817.2.patch,
 based on feedback @nacin and @markjaquith gave at WordCamp Orlando last
 week.

 We definitely need to get this bug fixed, and it needs to be done in a
 backwards-compatible way. A minor performance impact is probably worth it.
 I'm just not sure what the threshold is for "minor". 5% is probably too
 big. 1-2%, maybe even 3%, would probably be acceptable, in my opinion.
