Re: [Patch][RFC] Disabling per-tgid stats on task exit in taskstats

Like, a single message which says "20,000 sub-millisecond-runtime tasks
exited in the past second" or something.

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.
