Your concerns for this fix is quite correct, and is why this PR was closed
in the first place as there are a lot of ill-defined semantics introduced by
this.
Regarding your thought on relating idleness to empty results returned from
Kafka: I think that seems like a good approach, and should also capture Eron's
comment quite well.---
