Yes this would be very convenient on the client's side. But I also understand that this is quite complicated to implement on the lib's side, because it needed buffering of the data to read for an undefined period. We can't think of a channel as pipe, on which we can poll and the data stays there until we read it. The polling is always on the whole session and every channel of it. If there's data to read, we have to work on it for every channel. At least this is how I understand it... Till
