Andy Grove / @andygrove:
This failure happens consistently on my 24 core Threadripper desktop running Ubuntu but I cannot reproduce it on my MacBook Pro or on my work PC (6 cores, also Ubuntu).

I can’t reproduce this in my small ubuntu vm, even if I use .with_concurrency(50) on the test. So, it seems it needs physical units to reproduce.
