The default config cuttlefish creates says it is raising the limit on live processes to 256000 but the current limit, at least since R16, is higher than that, 262144.
It may still make sense to set a max ets table limit, but the docs incorrectly state "Raise the ETS table limit", there is no limit on the number of ets tables anymore.
Wasn't sure what people think the new limits should be (if any) is why I don't have a PR to include with this :).
