take() blocks indefinitely

It looks like the core loop is using up a lot more CPU than it should due to a busy-wait, correct? Would it be better to sleep between iterations?

Btw, thanks for the blog post and WatchService example! Even though I don't know Kotlin, I found it easy to follow.

Sorry, I got it wrong in my last comment. Using take() blocks here, but doesn't that mean it will continue to block until a change happens? Meaning if no change happens it will block indefinitely? How will it be interrupted? (Note that poll() would be a solution, but we would want to avoid a busy-wait with that approach. Maybe a better approach would be to interrupt directly, but I'm not sure how that is accomplished with coroutines.)
