In fact, I rewrote os.path.walk soon after having sent the message (in
a rush, as I really supposed to be doing other things in these days :-).
Initial testing did not bring me the speed gains I was expecting, that is,
not enough to be worth a change. But I'll rather suspect my testing than
my code, you surely know how presumptuous programmers usually are :-).
In any case, I'm putting this rewrite on hold for now, with the intention
of revisiting it later, for when I will have more free time before me!
