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.

Nah.  Stick it in the same cacheline as tasklist_lock (I'm amazed that
we've continued to get away with a global lock for that).
