  cPickle is a helluva lot faster.  Some tests have reported as much
as 1000 times faster.  Using "binary" pickles should help a lot in
either case, since the DOM data structures are heavily biased toward
string data, which is a lot faster in the binary format.
  The best combo is:

	*  cPickle if it's available (otherwise just use pickle), and
	*  binary format, in either case.
