Kobolds

Foreword

I have never, I'm pretty sure, read any official write-up of what a kobold is. Everything I know about kobolds is apocryphal and from various conflicting sources. That is, as far as I'm concerned, as it should be. I don't put much stock in official sources, anyway, because they mostly talk about how kobolds are inherently evil, which is garbage.

I'm trying to understand how Elixir's Port works. I'd like to interact with another command that's run and communicate over :stdio and detect when the other proccess ends in order to gracefully handle it. In my actual application, I'll send input to the other process, get the result and check it. If it's good, I'll repeat. However, if the other process exits after sending any result, my program should take some actions and then exit its self. This is meant to be normal behavior, not an error.

However, when I run the below toy script, I'm getting errors trying to deal with the other process exiting. The 3 other processes I wrote are meant to read one line, echo it back, then exit, while the toy script has 3 items to deal with (it should just do the first, then report exit and end).

Here's how it's running on my system:
