I gave this some more thought, even if we go with the throttling right away in
practice you'll end up with a dmesg notice of a throttle kicking in once you *do*
reach this. We are forcing only 50 concurrent threads and making this a static
limit with no good reason than 2.3.38 days evaluation from 16 years ago (2000).
If we throttle we are going to throttle with a 2.3.38 days limit. And you
advocate that ?
