ancestry = b.repository.get_ancestry(b.last_revision())

 11.4ms TIMEIT "json = simplejson.dumps(ancestry)"
101.0ms TIMEIT "xml = xmlrpclib.dumps((ans,), allow_none=True)"
 16.7ms TIMEIT "val = simplejson.loads(json)"
340.0ms TIMEIT "val = xmlrpclib.loads(xml)"


Now this is a huge list of strings. And the JSON representation is about
200kB, the XML representation is about 300kB.

But it does say that simplejson is about 10x faster than xmlrpclib at
dumps, and 20x faster at loads.
