Could we utilize a Thread/Task wrapper api to avoid duplicating tests like this? For example, like ExceptionCatchingTask/ExceptionCatchingThread.

Similar to how SpecRunnerThread/SpecRunnerTask work? We could move that abstraction up to be a generic class we use everywhere we need a similar pattern.

Updated #2094 for this use case.

await self.target(*self.args) will work even if self.args is an empty list so this code can be simplified.

Good point, we'd want it to throw an error here instead of being a silent no-op.

We should probably put a short sleep in here (5ms maybe) to avoid a tight loop.

Do we need to set stopped to try even when target raises? If so I suggest using try/finally.

Good point, I'd say so.
