In order to reach a good flow and transfer speed, you never let the window

cannot accept more data for the moment and then you tell the other side to
not send more by setting the window to 0.
What is a good method to wait for the window to reopen in libssh2? Should
ret = 0 be handled like EAGAIN? Or is some special handling needed?
The examples seem to busywait if this happens.
Right, this function should only return 0 if it truly sent _something_.
It shouldn't repeatedly return 0 if the window size is 0 as then it probably
not send anything at all and return EAGAIN instead...
I'm not ruling out a bug but this window size theory is only a guess so far.
