I believe Raymond Hettinger got sufficiently annoying with this being
pointed out <wink> that this will no longer be true in 2.3.  From the
whatsnew document:

  xrange() objects now have their own iterator, making for i in
  xrange(n) slightly faster than for i in range(n). (Patch by Raymond
  Hettinger.)

Cheers,
