That was my own conclusion after some grubbing around in the OpenSSH
source code (modulo the exact wording; see below).  Looking at my debug
traces, that sure seems to be exactly what's happening, and looking
over my code, I can see how and when it happens.

That's my reading too, which is why I suspected this of being a bug in
OpenSSH rather than in my code.

I can't attribute that to anything but a mistake by Nicolas.  There are
no "window-change" SSH_MSG_CHANNEL_REQUEST messages involved in the
cases I've looked at; SSH_MSG_CHANNEL_WINDOW_ADJUST messages are what I
was talking about.
