With the current implementation of concurrency, threads cannot
usefully signal anything: if a thread raises a signal that is not
caught, it simply dies. And you cannot catch such a signal from
another thread.
So your proposal would mean that the thread which runs the async code
sets some variable, and the application in the main thread then
signals an error based on that variable's value. is that what you had
in mind?
