Why the stdout.read() will hang if use dierectly without checking stdout.channel.recv_ready(): in while stdout.channel.exit_status_ready():
For my case ,after run command on remote server , the session is waiting for user input , after input 'q' ,it will close the connection . But before inputting 'q' , the stdout.read() will waiting for EOF,seems this methord does not works if buffer is larger .
