Comment 8 for bug 806761

Okay, after reading the Daemon Behavior section of the Upstart cookbook (http://upstart.ubuntu.com/cookbook/#daemon-behaviour), I've settled on a solution that I'm reasonably happy with: looping in a post-start script until the ticket cache is detected on the file system _or_ a timeout occurs (so we don't stall the job start process indefinitely)

Patch is attached. Contains the updated logic, as well as miscellaneous edits for clarity.
