Comment:
Replying to [comment:5 int-e]:
> throwAsync :: Exception e => e -> IO ()
> throwAsync e = do
> target <- myThreadId
> throwTo target e
nitpick: what if throwAsync is called when in blocked mode? does it need
to do `unblock (throwTo target e)` in order for the self-exception to
arrive? (or maybe the RTS already side-steps this deadlock?)
