I've seen software using bitmasks for processes. 4 million processes is just 512kb, bumping this by 1024 times might cause issues.

Aren't they already broken on systems with a raised sysctl setting?

No, they read the sysctl setting. They probably can be broken if it changes when the program is launched, but nobody really does that.

I'm not saying that such a design is a good idea, it's just that I've seen it used.
