well, I think it will prove what the cause of the hang is, if it makes the
hang go away.

The follow-up question would of course then be how EAGAIN can be returned
without a block direction gets set.

The logic is that only the transport layer can cause an EAGAIN, so the only
places where this should have to get done is in _libssh2_transport_write() for
outgoing data and _libssh2_transport_read() for incoming...
