Hi Kurtis,
Thanks for your detailed explanation. It all makes sense to me (I figured
out the race condition issue after I posted the question. As it was the
first time I posted to the group, I couldn't reply to my own question until
the moderator approved it).
For future me and other beginner
You have at least three problems. The first is a race condition in the
second, goroutine, version of your program. Add a `time.Sleep(time.Second)`
just before the `wpipe.Close()` and you should see the same behavior as the
non-goroutine version. That provides a hint regarding the primary problem.
