For the past month I have been running my nightly with RCWN enabled, and the racing thresholds set very low (value of 1). I think it would be very useful to get some preliminary data back on Nightly. I propose we turn on the pref, maybe also lowering the default thresholds, and see what happens. It would be great to see a spike in telemetry (in the right direction), and hopefully no new crash reports or regressions.

I think you can just land the reviewed code from comment 4 without worrying about pref-off.

yes, this data we need to meet our 57 goals. As for turning on the feature, I'm going to suggest a 1 day trial - get it into one nightly and then pref it off before you even know what the data is. you ought to be able to use the buildID to look at the telemetry, even though ime it won't come in for a couple days afterwards. also make sure you're familiar with the "nightly soft code freeze" memo ritu sent to dev-platform a week ago. I'll also ni ritu here just for his fyi.

Thanks for the heads-up. Marcia and Philipp who monitor Nightly crash rates are also aware of this now.

Valentin: We are seeing a pretty big crash spike - Bug 1367742#c2 which is now the #2 top crash suggests it might be attributed to this being turned on. How long will we leave this turned on?
