Huh - interesting. As far as we know we haven't received any bug reports from the Twitter team (although we have reached out to them - and they do have our contact information) regarding this issue. Additionally I don't think we've received any reports regarding selector performance regressions in 1.4.4. I'd definitely be curious to see what the issue is (and fix it for 1.5) but at least right now there isn't a whole lot for us to do (other than continuing to try and contact Twitter).
