We're still using Python 2.1 in certain areas, where supported
libraries for newer Python releases has only recently emerged.

But we're not using Quixote in production applications, only
internal stuff. So it's not a big deal.  I think the current
version of Quixote is stable enough to fork off the next
release to 2.2+.  Please just provide a stable link to the
pre-2.2 versions and document it as such.

The benefits of subclassing StringType outweighs the costs,
assuming Erik and I can continue to use older versions of
Quixote over the foreseeable future.  Erik?
