[paramiko] ctrl-c issue.

[Christian Vest Hansen]

Hi,

I have this issue, that when I connect to a server and exec_command on
something that'll take a long time to finish, if ever (like tail -f),
my script will only be able to respond to my local ctrl-c commands
when the remote program produces output.

This is the example program I use:
=================================================
import sys
import getpass

import paramiko

client = paramiko.SSHClient()
try:
    client.load_system_host_keys()
    hostname = raw_input("Hostname: ")
    port = 22
    username = raw_input("Username: ")
    password = getpass.getpass()

    client.connect(hostname, port, username, password)

    cmd = raw_input("[%s@%s]$ " % (username, hostname))
    stdin, stdout, stderr = client.exec_command(cmd)
    for line in stdout:
        print line,
except:
    sys.excepthook(*sys.exc_info())
finally:
    client.close()

=================================================

Steps to reproduce:
* connect to some server with normal ssh and $echo a >> my_file
* then use above program to connect to the same server and run $tail -f my_file
* then $echo b >> my_file and see the tail working
* then, in the shell with above program still running, press ctrl-c
* notice that pressing ctrl-c dosn't stop above program, regardless of
how long you wait
* now, in the normal ssh, do $echo c >> my_file
* only then will above program notice the term request and halt operation

What I want is for the program to terminate immediately when I press
ctrl-c, so the question is how I can I make this so?
