In 219, we wait for the job to make progress before we emit its status. This makes the output reliable.
Unfortunately, there is a bug: We do not wait for any more progress if the job has already reached its total-progress. Right after the job has been started, it is possible that total-progress is still 0, though. In that case, we may skip the first progress-making step and keep ending up 64 kB short. To fix that bug, we cab simply wait for total-progress to reach 4 MB (the image size) after starting the job.
