alt Hacker NewsTo the contrary, the projects I've been part of have had no end of issues related to being cancelled in the middle of a critical section [1]. I consider poisoning to be table stakes for a mutex.

Well, I mean, if you've made the unfortunate decision to hold a Mutex across await points...?
This is completely banned in all of my projects. I have a 100k+ LOC project running in production, that is heavily async and with pervasive usage of threads and mutexes, and I never had a problem, precisely because I never hold a mutex across an await point. Hell, I don't even use async mutexes - I just use normal synchronous parking lot mutexes (since I find the async ones somewhat pointless). I just never hold them across await points.
