It was decided that, at least for the first part of the e10s experiment on beta46, we want to do it with APZ turned off. It's on right now (bug 1178298), and it's better to have it turned off in the tree rather than let the experiment manage it.

[Tracking Requested - why for this release]: It was agreed on the e10s meeting today that apz should be turned off during the initial tests of e10s for beta46

Tracking for 46

Comment on attachment 8726833 [details] [diff] [review] patch From discussion on Friday, we plan to disable apz on beta 46 for at least a couple of weeks. Please uplift to aurora.

Felipe, we should back this out on Beta soonish, right? When does it need to land on beta to miss beta 2 but make it in beta 3 (assuming those are the relevant betas).

Kats, I just talked with Erin, and the plan is to make it to beta 4, which goes to build on the 21st. So if it's agreed to turn APZ for the next phase of the experiment, we should back out during the weekend

Thanks. I filed bug 1257181 to reenable, since I felt it would be cleaner to do it as a new bug rather than a backout in this bug.
