Well, the argument was that process / thread counts were a poor and
unnecessary proxy for kernel memory consumption limit.  IIRC, Johannes
put it as (I'm paraphrasing) "you can't go to Fry's and buy 4k thread
worth of component".

After some discussion, Frederic agreed that at least his use case can
be served well by kmemcg, maybe even better - IIRC it was container
fork bomb scenario, so you'll have to argue your way in why kmemcg
isn't a suitable solution for your use case if you wanna revive this.
