That still shouldn't have been _slow_,  but you're 100% right that it
was inefficient. I've taken a slightly cleaned up version of the patch
into 3.9 - along with a bunch of other ticket history perf work I've
been doing over the past few weeks, I think you'll find it to be a
pleasant change.

Thank you!
