Because TP5's memory measurements are meagre and usually fail to detect even obvious regressions. And this leak only occurred in unusual circumstances; AWSY is much better than TP5 at detecting regressions (though still far from perfect) and it missed this case too.

Why didn't TP5 report a regression in memory usage?

Note: like last time, cache2 will be turned on for nightly Firefox
desktop users only, and not for android/b2g. It will also not be turned
on for the buildbots, as we still have a few orange/perf bugs that we're
tracking down.
We have a number of people who have been using cache2 for their daily
browsing for quite some time, so we don't expect catastrophic failure.

Yes, that's exactly right. The orange/perf bugs are not major bugs, but they're enough to keep us from doing a full landing. But meanwhile a wider test audience is likely to shake out bugs that don't emerge from our automated test coverage. We found a few bugs that way in our last trial run. It'd be good to be able to work on those in parallel. > Do we have the telemetry or feedback channels in place to > measure what you need to measure? We'll be keeping an eye on telemetry measures like cache hit rate and response time. The other feedback channel is to alert engineers and other nightly users that this is happening so we're more likely to get bugs filed.

Enabling new HTTP cache on nightly (browser only, not automated tests) soon
In February we briefly turned on the new HTTP cache ("cache2") for a few

do this again starting in the next day or two--if this seems like a Bad
