paramiko ssh die with big output

When there is a limited number of files, all works well but when it's a big folder, the script wait unlimitedly. The following test shows me that the problem comes from the size of the stdout. (SO : http://stackoverflow.com/questions/31625788/paramiko-ssh-die-with-big-output)
Is there a way to correct that and execute this kind of command ?

Case big output :

query = 'cd /;ls -lshAR -h'
chan.exec_command(query)
while not chan.recv_exit_status():
    if chan.recv_ready():
        data = chan.recv(1024)
        while data:
            print data
            data = chan.recv(1024)

    if chan.recv_stderr_ready():
        error_buff = chan.recv_stderr(1024)
        while error_buff:
            print error_buff
            error_buff = chan.recv_stderr(1024)
    exist_status = chan.recv_exit_status()
    if 0 == exist_status:
        break

Result is (not ok - block - die ??)

Case small output :

query = 'cd /;ls -lshA -h'
chan.exec_command(query)
while not chan.recv_exit_status():
    if chan.recv_ready():
        data = chan.recv(1024)
        while data:
            print data
            data = chan.recv(1024)

    if chan.recv_stderr_ready():
        error_buff = chan.recv_stderr(1024)
        while error_buff:
            print error_buff
            error_buff = chan.recv_stderr(1024)
    exist_status = chan.recv_exit_status()
    if 0 == exist_status:
        break

Result is (all is ok)

Start with the channel usage shown around chan.exec_command, chan.recv, and chan.recv_exit_status, and reproduce the issue using the large-output ls command from the report. Trace how large stdout is handled and verify that the command completes and its output and exit status are received without blocking.
