If only there was some framework that already did this….
- There is?
- What is it
  
  BPF,
  or you can just use a CGroup.

  AFAIK you can't do this with BPF as it doesn't have any kind of sleep functionality. I'm also not sure how would you achive this using cgroup, which are about quotas AFAIK.
