Using Channel, I can write:

val upstream: ReceiveChannel<Int>
val downstream = produce<String> {
  for (u in upstream)
    u.toString()
}

This is essentially the map operation on a channel. Is there a way to run it in parallel (eg. Having multiple coroutines that read from the channel, process the data and send the results)? I can write an easy for-i loop, but it won't close the original channel.
