What it says on the tin. Testing of bug 907201 has not shown any regressions, so we should be good here. (Hopefully) final try push coming up.

Sadly, the xpcshell-test failure from the try run is real. The test_unique.js test crashes. And because things would be too simple otherwise, it doesn't crash when I run it under gdb. Jandem, can you take a look at the crash and tell me how best to investigate this? : https://tbpl.mozilla.org/php/getParsedLog.php?id=29602109&tree=Try#error1
It's an xpcshell signal handler issue, filed bug 931861.
I pushed this patch to Try again and I'm getting browser-chrome nsGlobalWindow leaks. Will see if I can reproduce this locally. https://tbpl.mozilla.org/?tree=Try&showall=1&rev=c47ae63c9c06
(In reply to Jan de Mooij [:jandem] from comment #8) > I pushed this patch to Try again and I'm getting browser-chrome > nsGlobalWindow leaks. Will see if I can reproduce this locally. I can reproduce it locally when I run a single test, even without the patch, so it's likely a pre-existing issue. With help from :smaug I'm still trying to track it down. I wrote a patch to fix xpcshell (bug 931861) and it's green now  so hopefully once we fix the BC leaks this will be good to go...  https://tbpl.mozilla.org/?tree=Try&rev=a6a2b1fbf40d
I'm trying to track down the Linux-only, opt-only Mochitest-BC nsGlobalWindow leaks when I turn on TI for chrome, but I can't reproduce them locally so I have to use Try. Unfortunately the BC suite takes more than an hour to run so this takes a lot of time :( But at least it's not a Win32 PGO build or an intermittent failure...
More info: with Baseline disabled, it's green. Baseline enabled without attaching IC stubs is also green. So there's likely an IC stub that's keeping stuff alive. Will try to narrow it down with more Try pushes...
Bug 970645 fixes the Linux Opt nsGlobalWindow leaks I saw on Try. I also posted a patch for the xpcshell issue, bug 931861. Will do another Try push once these bugs are fixed.
Yet another problem: a Linux-only profiler assert with Mochitest-BC in debug builds. With the patches in bug 832437 and bug 931861 everything is finally green on Linux x64: https://tbpl.mozilla.org/?tree=Try&rev=c641fd52bec4
