Out of curiosity, has anyone tested libssh2_sftp_readnb() across a
slow connection that would actually block? I have never seen it block
in actual usage, because there is still a blocking transaction when
each ~30k packet is sent, so if your connection is going to block then
you are probably (in my experience) still going to block on that
initial required response rather than the actual data packet.
Daniel has done a lot of good work under the hood to prepare for non-
blocking support at this higher sftp level, but a little more work
will need to be done to get pure non-blocking behavior from all sftp
operations. I'm happy to hear you are taking this on Jim; I am
definitely interested in seeing non-blocking support in libssh2 improve!
