Thanks for pointing out 1369955, Nick. It looks a little dormant at the moment, but that is not at all the case; It's my main focus this quarter.
I think it's worth pointing out that the features the Gecko profiler offers - integrated C++ and JS stack sampling, markers - would be just as valuable in the shell as they are in Gecko. I would like us to provide these features at some level that's shared by both the shell and the browser; tools/profiler is Gecko-specific. But I need to build up some support for this approach first.
