At the end of the way you will need to poll something, be it for the output file or the status of the job.

But the sleep could be way lower; 50ms would be perfectly fine.

@WencongLiu Could you lower the sleep?

[WencongLiu]

Done. thx @MartijnVisser @zentol

@WencongLiu You'll need to rebase your PR with the latest changes from master to get the CI to pass.
