Review Comment:
> we must drop memLimit and the fixed length pending queue
Sorry, I am not get the point why we should drop the memLimit? It's a useful
feature for the users who is lack of resources.
And I don't think the `fixed length pending queue` will become a problem to
`SendAsync`. Why should we make it flexible?
