A bare-metal super-loop is preferred to a kernel when the application has

  • A.many activities with widely different periods and tight deadlines
  • B.a requirement for a TCP stack and a file system
  • C.several developers working on independent subsystems
  • D.few activities and generous, well-separated deadlines

Answer: D

A handful of things to do in turn needs no kernel, and the loop is smaller, cheaper to certify and easier to reason about. The moment the periods and deadlines diverge, hand-scheduling them in a loop becomes the harder problem.
