I don't think Talos profiling currently supports e10s adequately. I'm aware of two problems:
 - It calls dumpProfileToFile, which is synchronous and will not include subprocess profiles.
 - It's not very intentional about what process it calls nsIProfiler functions in. It needs to collect the profile in the parent process, but pausing + resuming the profiler may sometimes be more appropriate to do in the content process.

We'll need to look at each Talos test in turn and determine whether it supports profiling adequately.
