Subprocess example: Child process not closed during test

[loynoir]

https://deno.land/[email protected]/examples/subprocess

Deno.test("example", async () => {
  const cmd = ["echo", "hello"];

  // create subprocess
  const p = Deno.run({ cmd });

  // await its completion
  await p.status();
})

A child process (rid xxx) was started during the test, but not closed during the test. 
Close the child process by calling `proc.kill()` or `proc.close()`.
