System wide accumulation of such data in the exit() code path still
risks being a bottleneck, just a bit later on.

I'm more inclined now to look for ways to disable collection on some
CPUs, and/or to allow for multiple streams in the future, as need be,
along the lines of Shailabh's multiple TASKSTATS_LISTEN_GROUPs.
