Upstart blocking - is it a problem?

You should add a "service" stanza to your job file. If you have it or "restart" stanza, initctl exits once your main process is started.

Missing "service" is not very serious omission, it only affects the initctl command, init itself continues running and processing other jobs and events asynchronously. I think there are quite a few jobs in system sw that misses it.
