Well... excluding potentially having to grab the file off the network
somewhere, which would be the slowest operation.  That's why in my code I
check if the external DTD is in my map, and if so, use a local copy.  If
the pickling sped it up by another factor of 4, that would be great.

I would be very interested in this.
