--- Comment #1 from Damien Miller <djm at mindrot.org> ---
> It seems like channel_pre_open() excludes the channel from ppoll when remote_window == 0 and this creates a deadlock - can't receive window adjustments if you're not polling (but take this with a grain of salt I have no idea what I'm really talking about here).

That is not the case: window adjustments are received over the ssh
transport not from the channel fd.

Can you get a dump of the channel status, e.g. using the ~# escape
character?
