> Is there something less cooperative than a task that doesn't yield its control back to the main thread? Of course it does yield back to the main thread in my example, at each await point, just like any other cooperative task.

In my case, I specifically want an independent execution of a task. Admittedly, it has to catch its own exceptions and deal with them, as you pointed out, because that's part of being independent.

(Technically, in issue A it doesn't crash the running thread. The event loop catches the exception, but it complains later when the task is garbage collected. Issue B is fine for my use - when the event loop shuts down, it cancels remaining tasks, which is exactly right for my server.)
