Please STOP replying to messages when you want to create a new
thread. This causes problems for search engines and humans who use
threading as a means to organize related messages as a whole
discussion in their email software. When you are creating a new topic
make sure to send a new email, or at the very least make sure that
you remove any RFC822 headers in your message that link it to
previous posts. (This is not possible in many email programs, so the
safe method is to always send a new email when starting a new topic!)

Yes, and you must be using non-blocking. This is a known deficiency
in the libssh2 API that is being worked on.

Then they all return _EAGAIN.

By reading from any channel the library will try to read from the
socket associated with the session that the channel belongs to. If
there's data to be read then it ends up on the right channel.

If by polling you mean _channel_read() then yes.

Then there won't be much data. This case isn't covered at all by the
current API. It's an important point to keep in mind for the future
improvements.
