I'm just starting my use of libssh and am having problems reading output from 
an executed command. I've read the docs & tutorials but haven't found anything 
to address my problems.

My basic sequence goes like this:

1: connect & auth
2: ssh_channel_new, ssh_channel_open_session, ssh_channel_request_exec
3: loop on ssh_channel_read_nonblocking to read all output resulting from 
starting the command
4: ssh_channel_write to send some input to the command. this results in the 
command generating some output response
5: loop on ssh_channel_read_nonblocking to read all output resulting from 
starting the command

The problem is that at #5 there is no output data. If I sleep for 3 seconds 
before reading the output then I get the output that I already read at #3.

What am I doing wrong with this basic scenario?

-Wes
