The per-process mode works fine after moving the trace point to be after:

        perf_event_task_sched_in(prev, current);

App developers using this feature here say they're fine not having the 
block vs sleep distinction because they intend to use it with "-g" and 
the callstack makes it obvious which one it was.

If we really need this info, we should be able to derive it in user 
space via perf inject.
