Code review comment for lp:~xnox/upstart/shrink-notifications

Still racy I'm afraid:

not ok 48 - with single-line command running an invalid command, then a 1-line post-stop script
        wrong value for child_exit_status[1], expected 255 got 0
        at tests/test_job_process.c:3193 (test_start).
Aborted (core dumped)
ERROR: failed on iteration 6
