Running long script in the background

[wattersmt at gmail.com]

Hello,

I am trying to write a python cgi that calls a script over ssh, the
problem is the script takes a very long time to execute so Apache
makes the CGI time out and I never see any output.  The script is set
to print a progress report to stdout every 3 seconds but I never see
any output until the child process is killed.

Here's what I have in my python script:

command = "ssh -l root %s /scripts/xen/xen-create-win-vps1.sh %s" %
(host, domuname)
output = os.popen(command)
for line in output:
   print line.strip()

Here's a copy of the bash script.

I also tried using os.spawnv to run ssh in the background and nothing
happens.

Does anybody know a way to make output show in real time?
