@bothejjms Sorry, there's a typo in my previous comment: it was 45 seconds
on my machine and it literally killed the entire machine which I think isn't
acceptable on Jenkins slaves.
I'd give it a try with ThreadPoolExecutor at the first place and dig into
why it's not 100% reliable currently. If there's no success with a few days
work, just skip adding test here.---
