Should I use threads here?

Hi again,

Reading now a new email on the group "Strange Tkinter behaviour"
I realized that probably my problem has to do with the Tkinger widget.
So, I just inserted a
    self.text.update()
and the output starts imediately apparing, as I wanted.
The widget is sort of "frized" while the .exe program is still
running (cannot scroll), but perhaps I can arrange that later.

Anyway, pointing out the difference between readline() and readlines() was
absolutely right from your side. Now that I added .update(), I checked both and 
only readline() does what I exptected.

So, really thanks and sorry for bringing out the question of threads.
I just have to understand better some os stuff.
