Many VM (I am assuming the machine is a VM today) system support screen shots.
We take screen shots at regular intervals during the reboot process. We then
take the md5sum of the bitmap (much easier than "parsing" the image content),
once the expected screen is up it is ready for the next job.
In summary:
1. Job ends with success and schedules reboot.
2. Job waits for reboot to complete, fails if timeout elapses.
3. Job finishes tests.
