11:58:37stassatsi have no idea really what dual-channel-p is supposed to mean, but synchronize-stream-output synchronizes an input buffer on an output stream
12:00:47stassatsok, it's for sockets, but synchronize-stream-output still shouldn't touch the input buffer if there's none
12:04:53stassatsis it even worth salvaging the IO system or a new one should be just rolled out from scratch?
