consecutive runs of "init-checkconf" produce errors

I am trying to programmatically run `init-checkconf` on the entire /etc/init folder and seem to have found a race condition. Basically I want to do something like `for UPSTART_JOB in /etc/init/*.conf; do init-checkconf $UPSTART_JOB; done` but find that I can't do so without putting a sleep after each check.

How to reproduce:
`init-checkconf /etc/init/atd.conf && init-checkconf /etc/init/cron.conf`

Expected results:
File /etc/init/atd.conf: syntax ok
File /etc/init/cron.conf: syntax ok

Actual results:
File /etc/init/atd.conf: syntax ok
ERROR: failed to ask Upstart to check conf file
