Just tried various code, but no output since the time time ends:
import time
import web
urls = ("/", "hello")
class hello:
def GET(self):
for i in xrange(3):
yield "hello\n"
time.sleep(1)
app = web.application(urls, globals()).run()
My browser "wait" 3 seconds and after show me the whole page.
Just thought that one of the "simpliest" way it's to save somewhere a
shared state, create an iframe (where show the progress) that reload
every n seconds. Create a "/internal_progress" page (class) that serve
the separate (iframe) page and return the state. When ends, show a
"goto" button into the iframe.

It's more or less my idea :) , only that I not use (or much less)
javascript.
I'll look at it!
Thanks,
