I have a `produce { }` that sends download status to a notification service, so if there's an exceoption I'd like to be able to send an error message. It looks like `try { } catch() { }` is unreliable (<https://github.com/Kotlin/kotlinx.coroutines/issues/361>), and installing a `CoroutineExceptionHandler` on `produce` I won't be able to get to its channel to report status... is there any better way to do this?

`produce` already does what you want:
&gt; Uncaught exceptions in this coroutine close the channel with this exception as a cause and the resulting channel becomes _failed_, so that any attempt to receive from such a channel throws exception.

and after failure you cannot send “regular” message, because `produce` has the same lifecycle as its channel
