- mochitest-bc continues to be extremely timeout-prone. Evaluating options like splitting devtools into a separate suite (bug 984930), pushing harder on chunking work (bug 819963 and deps) which jmaher has gotten little support on, closing the trees OOMpocalypse-style, etc.
- Stability
- Other

<Read Only>

Firefox OS Media Recording (cjku)
Firefox OS Performance (mlee)
- Updates
- Flame (mozilla reference device)
- Power Perf: Has a switchable USB charger, so we can take power measurements while the phone is plugged in via USB.

- Flame (mozilla reference device)
- Mercurial Bisect Bug
- Dave Huseby conclusively showed last week that mercurial's topographic sort for bisecting BREAKS when the "oldest" end of the bisect range isn't a common ancestor.

- Dave has a blog post in the works to explain all of the details (with pretty graphs) and why mercurial breaks.
- Find Dave (:huseby) on IRC if you hit this problem.
