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:

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
