[mod_python] http 1.1 persistent connections

Hi all,
I'm new to Python and mod_python - and I'm having trouble finding out if mod_python supports  http1.1's persistent connections.  

I need to be able to have long-running scripts flush a single document - a little at a time, as it's generated - out through Apache to the client.  It might take a minute or an hour.  

Cold Fusion makes this dirt simple.  You can simply insert <cfflush> anywhere in your template and whatever data is generated thus far will be flushed out to Apache - which will hold the HTTP connection open until the template finishes executing.  It can be kept open for hours and makes a good sort of server push.

Can this be done with Python/mod_python?

 - thanks,
