>
> For non-zygote child gpu thread, start the trace thread in
> ContentMainRunnerImpl() directly.
>
> For zygote child gpu thread, start the trace thread in RunZygote after
> zygote fork and featurelist init.
>
> For Linux & ChromeOS, stop and restart the trace thread when entering
> sandbox. Restarting trace thread has a caveat that delayed tasks would
> will be lost unless we save them.
