My more-recent series is on top of 2.4, but (for webkit): mine: 0m0.206s duy's: 0m0.107s

However, I'm getting occasional index-helper segfaults due to istate->last_update being NULL. (I'm using Duy's index-helper branch from his github + this patchset + a function signature fix due to a newer version of libwatchman). I haven't looked into why this is -- maybe accidentally mixing git versions while testing?

Also, after messing around for a while (on Duy's branch), I ended up in a state where git status would take ~2.5s every time. The index helper was alive but evidently not working right. Killing and restarting it worked. Actually, I think I can repro this more easily: "git rm Changelog" seems to put the index-helper into this state.
