Great, now we're at least narrowing it down.

-21 is LIBSSH2_ERROR_CHANNEL_FAILURE and it is only used in a few places.

Can you check what error message string libssh2_session_last_error() returns
after you've got the error? It should help us to pinpoint exactly which of the
channel failures it was.

Right. If we're lucky you get the error at src/sftp.c:198 (as that's marked as
a TODO and I know what the problem with it is and what we should do to fix
it....)

I think the main reason I haven't seen this problem is that I've only tested
on Linux and I figure the TCP stack differences are big enough to be important
here.
