Documentation: Misleading comment in event driven discovery #460

Specifically those lines:

    // Print based on whatever the event receiver outputs. Note that the event
    // receiver blocks, so in a real program, this should be run in its own
    // thread (not task, as this library does not yet use async channels).
    while let Some(event) = events.next().await {

This comment is probably a relic from a time where instead of events.next().await there was a blocking call, right?

I can hardly imagine that events.next().await requires its own thread; this thread would require a new async reactor because it can no longer process .await calls. So I'm highly suspicious of this comment.

Also, the fact that events is some implementation of futures_core::stream::Stream, I question the validity of does not yet use async channels.
