The EAGAIN returned from adjusting the receive window is not really EAGAIN,

I don't get this explanation.
In the function _libssh2_channel_receive_window_adjust() there's a call to
_libssh2_transport_send(). If this transport function returns EAGAIN, then
that will be returned from the receive window function. All other errors will
cause a LIBSSH2_ERROR_SOCKET_SEND to get returned.
I don't see how the receive window function would cause a BAD_USE return code.
Can you elaborate?
If we don't receiving data until the window-adjust packet sent. Actually we
will wait until all request packets sent(4 * buffer_size / 2000).
Why? There's a check of the window_size in every call to
_libssh2_channel_read() ?
