This story begins, as they so often do, when I noticed that my machine was behaving poorly. My Windows 10 work machine has 24 cores (48 hyper-threads) and they were 50% idle. It has 64 GB of RAM and that was less than half used. It has a fast SSD that was mostly idle. And yet, as I moved the mouse around it kept hitching - sometimes locking up for seconds at a time.

So I did what I always do - I grabbed an ETW trace and analyzed it. The result was the discovery of a serious process-destruction performance bug in Windows 10.

Great story.

I understand that, but because there are many readers on this side with great technical insight, I am interested if someone knows why thread creation is used instead of fibres or a threadpool when threads are expensive either way.
