`node:child_process.fork` does not generate cpu-prof when process is killed

Is there a required condition? Always ### What is the expected behavior? Why is that the expected behavior? When a child process is killed with `.kill()`, it does not generate the CPU profile that `--cpu-prof` argument instructs it to do. I would expect profile to be generated. This is inconsistent with `node:worker_threads` where terminating a `Worker` with `.terminate()` does still generate the …
