Part of the way. The last bit is to de-duplicate all of the Profiler.js
scripts in talos, and get them to use the asynchronous mechanisms for
profile gathering and writing (since they're currently using
dumpProfileToFile, which prevents us from getting out-of-process profiles).
That'll be in bug 1
Thanks Mike for your hard work pushing this through!
In theory it does let us profile e10s on TAlos, but I'm sure well will find
more usability issues. It's unclear if they will be a blocker or not. If
there's outstanding issues I don't think we know about them. Please file
them and CC me on any i

Does this get us all the way to "profile talos runs with e10s
enabled", or are there still pieces missing for that? IIRC this set of
patches was a prerequisite for being able to do that.

Just a heads up that there have been recent developments with regards to
gathering SPS profiles from multiple processes.
Bug 1103094[1] recently landed in mozilla-central, which makes it so that
if a subprocess starts up _after_ profiling has already been started in the
parent, then the subprocess
