I use it into a cgi script, with apache, and for my IRC like, I must do
a thing like :
    while 1:
        strLine = self.pRoomFile.readline()
        while strLine:
            sys.stdout.write(strLine)
            sys.stdout.flush()
        strLine = self.pRoomFile.readline()
        time.sleep(1)

And the lines I print don't appear in the browser
