Exit status consistency issue

When you raise in a file, then check your exit status from the terminal, you'll see 1, but it seems if that raise comes from within a Process, then you don't get that status code:

# test.cr
raise "test"

# run.cr
exit Process.run(
  "crystal run test.cr",
  shell: true,
  input: STDIN,
  output: STDOUT,
  error: STDERR).exit_status

# $ crystal test.cr; echo $? #=> 1
# $ crystal run.cr; echo $? #=> 0

I expected running crystal run.cr would return a exit status code of 1 but got 0.
