I've choose to display one line a time in the window
while 1:
data_o = child_o.readline()
textbuffer.insert(textbuffer.get_end_iter(), data_o)
textview.scroll_to_mark(textbuffer.get_insert(), 0)
while gtk.events_pending():
gtk.mainiteration(gtk.FALSE)

And also I choose to set the cursor position at the end of the output, like if
it is displayed in a *NIX consolle.

It helps a lot not just a bit, the only problem I have to solve noe is how to
exit from the loop in the right way, if I place a return at the end of
while gtk.events_pending():
gtk.mainiteration(gtk.FALSE)
just one line will be displayed, if I leave the loop open it wont stop so I
cannot, for example, call the mainquit().
I've read the faq but if the solution is there I haven't understood :p
