@NicoK , I have fixed the above issues you mentioned. I should double check
the typos after submit next time.
I agree and understand your feeling of
`RemoteInputChannel#releaseAllResources()` which seems destroy the beauty of
recycle. I would consider this issue and try to find other options if possible
later. And I think this will not block the reviews of following PRs. :)---
